Attached are pics of a 59 door that never had the door panel off before today. It's a power window car. The penciled "69" is on the inside of the outer skin. The green "93" in grease pencil is on the inner surface of the door (the door panel sits flush against it.) The other picture is backlit, and shows the "93" on the outer surface, but with the backlighting you can make out "PW" and "03" on grease pencil on the inner side (window guts side)of the inner surface. It's clear that the power window assembly was placed in the door before the skin was bonded on. Anyone ever seen evidence of this on a manual window door? I remember seeing the remains of a 61 power window door in a junkyard in San Diego in 1981--part of the skin had been torn off in the accident, and I saw the power window parts and the "PW" in grease pencil on that door also.P5310982.JPGP5310986.JPGP5310985.JPG

Re: 56-62 door build sequence
I don't know about manual window cars, but my 61 power window car had 529 crayoned in on inside both doors. The 529 is the last three serial numbers of my VIN and is also found crayoned on the inside of the firewall. -

Mike,
I found this back in the Archives a bit and thought I’d resurrect it. Interesting post! Now we know that a PW in grease pencil (green?) can be found on the inner skin inside of a Power Window car. I’ve never heard anyone mention this before. Any idea what the penciled 69 on the outer skin inside, and the 03 in grease pencil (also green?) on the inner skin inside means?
Now that you’ve got me started on this subject, I’ve got a few related questions that maybe someone here can add to, debate, speculate, or answer.
1. Did the power (PW) & manual (MW) window options both use the same inner fiberglass door skin in a model year? Or were there modifications in the fiberglass to accommodate the different manual & power internal mechanisms?
Mike’s picture shows a 1959 PW option and my picture above shows a 1962 MW option. In my MW picture the horizontal step in the fiberglass inner skin where a metal plate would be riveted for 1962 extends to the large access hole, where in Mike’s PW 1959 it stops short rather than extending through the 93 Job # to the access hole. Before someone calls me on it; I realize one is a 1959 and one is a 1962 and the inner molds may be, and probably are, different for each year. The 1962 AIM seems to support that the same inner skin mold was used for both PW & MW by stating that four of the eight attachment holes drilled in the skin for the MW regulator assembly or the PW regulator & motor assembly should be filled with resin, as four holes are used and four holes are unused due to different attachment points for each option. Also for MW option two additional small holes drilled and used only for PW option are to be filled with resin. This is a total of six drilled holes filled with resin that would have been used for PW option if instead using the MW option.
2. Mike states; “It’s clear that the power window assembly was placed in the door before the skin was bonded on.” Makes sense to me. Clearly the metal internal reinforcements and braces had to be in place; it would be pretty hard to spotweld anything through one of the access doors if inner and outer skin were first bonded together. And instead of working through small access doors it would certainly be easier, and probably faster, to also install most of the internal mechanisms (Motor and/or Regulator Assy., Window Guides & Runs, Lock Assys., Bumper/Stop Assys., etc.) regardless of PW or MW option before the inner and outer door skins were bonded together. Seeing a coating of Ermine White on the assembly attaching screw heads and shaft ends in my pictures above, and in Mike’s case Inca Silver, seems to reinforce this, as nothing was painted until the entire body with doors attached entered the paint line. I also think that they would want as much as possible of the final weight added to the door before adjusting it to the body for fit and tolerance. Also according to my picture above it looks like the window Garnish Moulding was in place before painting.
If all of this is correct (?) then what was NOT in/on the doors after they left their sub-assembly station marked with their green J/B #? And what was NOT in/on the doors just prior to painting? My guess is; trim panel, interior knobs & handles, door post assy., reveal moulding & end, weatherstrip, exterior door handle & lock, and inner skin access doors.
When was the door Glass put in place?
You can see the beige color of the fiberglass skin showing through the Inca Silver in places on Mike’s picture of the 1959. That green 93 Job/Broadcast number sure is bright and pretty ………. almost looks like it is on top of that Inca Silver instead of under.
Constructive criticism and corrections always welcome, as that’s how we learn.

Re: 56-62 door build sequence
Mike,
I'm in the process of restoring my 59 sn#1084. I have the same pencil making ins in the passenger door. I could not figure out what that was. Since the car have been painted at least twice in its like any grease pencil marks are gone from the door, however I did final at 96 in green on the passenger side of the speaker grill. There is something on the driver's side but it's unreadable. I tried posting some photo, but I've never done this before. Hopefully they will transferComment

Re: 56-62 door build sequence
Pat,
I know you asked for Mike, but I'm going to try and lend a hand. Look for the recent thread; "62 door markings". In it you will find my post and pictures describing where to find 3 out of the 4 Job/Broadcast numbers that I know of. Look inside your instrument cluster for your best bet at finding one and then compare it to the 96 that you found. They should match.
I know what you mean about first time posting pictures. I posted my first one yesterday and had one @!$$ of a time doing it. Today I did a bit better. I'll try to walk you through what I did.
1. First I loaded the pictures from my camera card to my computer in "My Pictures" in a special file for certain Corvette photos.
2. Then in the Tech. Forum click on either "Post Quick Reply" or "Reply to Thread"
3. In the tool bar 4th icon from the right (a square with dotted corners), put the cursor on it and it will say "Insert Image". Click on it.
4. An "Insert Image" window will pop up.
5. Click on "From Computer"
6. When this window appears click on "Select Files" at the bottom.
7. This should take you to your computer picture files. Figure out which ones you want. You are limited to 4 pictures per post.
8. Put the cursor on a picture you want and click on it.
9. All your pictures will disappear and the picture file number will transfer to the "Insert Image" screen.
10. If you want a 2nd picture repeat the process #6, #7, #8. You have to do this for each picture you want.
11. When you have the picture file numbers you want loaded on the "Insert Image" screen, click "Upload File(s)"
12. Your picture(s) should transfer to your post.
I just walked myself step by step through the process, and here is the picture. I found out that you can drag and drop the picture on the post. Good luck getting it exactly where you want it as it seems to have a mind of its own. I don't know which is better; write message first and then insert pictures or insert pictures first and then write message. Took me a couple dozen tries and five log outs the first time to get it right. Hope this helps.

Re: 56-62 door build sequence
Bill,
It looks like the only difference between the 59 & 62 inner skin might be the horizontal step in the center of the panel. On the 1962 panel this step continues to the large access door which on your 59 would cut right through the J/B# 24. On your door you can see the four holes that would have been used for the motor & regulator if this was a PW option. According to the AIM these holes were supposed to be filled with resin. If you still have the door available check for us to see if the assembly team actually filled these holes with resin or skipped it and left them open. Also according to the AIM there should be two more holes used for the PW option that were also supposed to be filled. They are supposed to be about mid door partway up and partway down but I don't see them on your door or my 1962 picture either. If you have an AIM check out the Power window page toward the rear of the manual and you will see where these two holes should be located on the panel.

Re: 56-62 door build sequence
Oops, the holes I was referring to are on the Manual Control Window Door page which in my 1962 AIM is Section F, Sheet 10.00. Two holes are covered by the regulator. There are six total, designated by a NOTE 2 in a square box.
