Wording a previous post on hood supports to include all midyears. I understand that the 63 and 64 Atwood hood supports did not have blackened washer or washers. Also understand that all the midyears had the number 16077. Now I am wondering who made this part for GM other than Atwood. Asking that question because some of these parts are appearing with no Atwood and Rockford, IL on them. My FI 63 has the support on pass side. So now what is the difference in construction of this part for say the 66 and 67's compared to the earlier years? I understand from the previous post and emails that the OEM supports appear to have Atwood. Later ones are supposed to have a blackened washer and that a kit from a repro dealer has the rivet and washer. This is all the info I have. I also understand that the last available GM one would not be correct for a 63. So with that what is the big difference please. Thanks again, John

John:
63-67 replacement part was 3797079 (parts book rev. = 6-79) group = 8.015 - I have one in box number 36, but not near where I am sitting. Think I also have a 67 Orig. - that has been sandblasted... I'll look some more.
At that time (6-79) you could still order the one for 58-62 also (I didn't). that was number 3739384
I thought they all came from Atwood in Rockford - Still in business.

Re: Midyear hood supports - Service #
Tom, Another I am confused on is the part number. I know the number you just posted is the Chev #. Put the part is stamped 16077. But of course this problem is often encountered. I imagine I am going to hear that the 16077 # was changed to a later number when there was a revision. This is what I am looking for. What revision caused this number to be changed. That way I will be able to spot later hood supports and repros on the earlier models. Thanks for your imput, JohnComment

Re: Midyear hood supports - Service #
Hi John,
The support assy. is listed in Oct 1, 1962 parts book in group 8.015 as GM# 3797079 and the same number is used in my March 1983 parts book. It looks as if the part number stayed the same. I will look at some of mine tomorrow and see if I can tell any difference.

Re: Midyear hood supports
Thanks to all for looking at the "Atwoods". It appears we are on to something here men. I have got a ton of emails on the hood supports. Lots of guys don't go onto the DB for some reason or another. It seems that most everyone that has an original midyear hood support has no black washer. Where does the black washer thing come in at? The reports I am getting is that the black washer thing is the minority. Most all the original hood supports do not have it. I would guess I have gotten at least 40-50 emails. But still one big unanswered question Peter and others. WHAT IS THE DIFFERENCE BETWEEN THE EARLY AND LATE HOOD SUPPORTS??? Some of you rebuild this things and sell them. How about some imput. Thanks very much, JohnComment

Re: Midyear hood supports
Jim and others, I have a possible solution to the hood support mystery. WE need a copy of the blueprint for the 16077 hood support. This number is an Atwood number not a GM number. Two friend wrote in and told me this and I guessed it anyhow. So if anyone in Rockford, IL from NCRS or otherwise has a connection we would most certainly appreciate some technical help. Need to read the specs on plating and changes throughout the model year. Thanks, JohnComment

Re: Midyear hood supports
On my 67, which I believe original, it has ATWOOD, Rockford, IL but I didn't find a part number. Is there a particular area I should look for a part number?

Re: Midyear hood supports
Rick, Interesting find on your original 67 hood support. Do you feel that it is original and not a GM replacment first of all? Meanwhile your info seems to fit what I have been finding. The 16077 and the Atwood logo are a hit and miss situation. Sorta like the 65 fuel injections having the serial number of the car on them. We would like to think that all had the number but it just wasn't so. We would like to think that a typical Atwood hood support would have had their part number and their logo. But so far the emails and posts I have been receiving do not back up this statement. Maybe the workers were supposed to have stamped every part but failed to do so. Not going to say anything about judging these things as it's too early. Not enough imput from car owners. I would guess I have received maybe 50 to 75 replies. Enough to realize that it has been an overlooked item on midyears as far as originality goes. The hardware seems to get more attention than the actual part. The black washer theory may be out the door also. Meaning only a few of the untouched originals have a blackened washer. Most do not. But no conclusions are being made at this time. More research is needed. Thanks, JohnComment

Re: Midyear hood supports
John,
I do not know for sure if the support is an original but most of the parts on the car have been determined to be original. The normal wearable parts excluded, the sidepipes, horns, distributor, headlight motors,etc. all appeared to be original with proper date codes. So my guess is that the hood support is original. To add to my conclusion that it is most likely original was that the car was unhit and never has had the body off as the tape holding the body shims is still in place. Hope this helps. Also, where would the part number be stamped? I have looked pretty good at the support but if someone could supply the general area where the stamping would be, that would help as my old eyes this late could use some assistance.

Re: Midyear hood supports
Rick, It appears that the so called part number would appear on the side closest to the fender. But I have another guess on this 16077 number. I think it is just the Atwood part number for this particular section of the hood support. Just the one section. Reason for this speculation is that a 69 to 71 hood support I saw also has this 16077 number on the same section. So maybe I have hit onto something here. If your hood support has ATwood but no 16077 don't worry about it. A lot of guys have written in with the same deal. In fact a 64 owner just wrote in tonight and said his support has no black washer, has the Atwood logo but no 16077.Some have written in the opposite info. Part number and no Atwood, etc. But the NOS replacements appear to be void of both the number and logo. Strange part for sure. Thanks, JohnComment

Re: Midyear hood supports
John. I checked my 63 support, which I believe to be original, but re-cad plated. NO Atwood. Has the number only. Can't comment on the washer. It's cad now. Chuck1963 Corvette Conv. 327/360 NCRS Top Flight
