63 alternator boot

Re: 63 alternator boot

That would be consistent with the first design used in '63. Note the lack of the inner rib used in the '033 part to match the ring in the alternator insulator used in later production. Time from print change in December until implementation in our plant and use of available inventory would be carried on the change notice, which is unavailable given the current status of what became Delphi corp, so the actual change date on the '63 models will have to be determined by original cars. Appears so far the first design went thru February, maybe some owners of original March-April-May cars will chime in.

JD's car is 9916 which is March 2nd or 3rd. Has the ORIGINAL alternator boot on it.

Re: 63 alternator boot

I have a early 63 with the original boot on the junk original harness and it looks like the boot in Bob's first picture. I installed the boot on the NOS engine harness purchased from GM a long time ago. A few of the wire colors are different but it was not worth fixing the original it was so bad.

I also have May and July dated 628 alternators and they have the new style insulator. One of them came with the red wire cut and the boot was still on it and it's exactly like the original on my car so Mike Hanson may be correct in that the insulator changed but the boot stayed the same until the 64 part # harness. The new style boot and insulator are so much better.

Re: 63 alternator boot

John;

You know, you really have enough information here to do an article for The Restorer Magazine.

I was out working on my car this morning and really got my nose down there to take a real close look. I have to rescind what I said in my earlier post. Mine does have the thicker lower tee piece on it, like the one shown in Wayne Midkiff's post of 4:09 pm yesterday. Mine is a July 9 build #19,147, and I have no reason to believe it has ever been changed since I took delivery 10 august 1963. That's not to say it is impossible as I did hit a deer in 1992, but the work should not have involved the Alternator in any way, nor do I have a receipt itemizing any such change. I did have my Alternator rebuilt, but again that did not involve the harness.

Perhaps a survey is in order.

Re: 63 alternator boot

Stu, I didn't know you were an original owner of a 63. I will have to pay more attention to your comments.
It would be a nice thing if someone here would write an article with a ton of pics using a lot of hese posts in the article as is.
I don't think I have seen this done. An article for "THe Restorer" written up using DB chatter responses. Since Jorjorian has so many pics maybe he will do it. JD

Re: 63 alternator boot

These are probably not '63 design, going by what others have said and shown, but here's 2 Delco types, and the bottom one is on a repro harness, that differs in multiple ways. The two views of those on the left are what I always thought were applicable to C2's (but now obviously not ALL '63s). The 2 views of the ones on the right have that thick web on the bottom with a different general shape to the bottom. I'm sure I've seen ones with the "bottom tee" (ie. similar to the ones on the left, minus the top ridge).

I was just out in the garage and mine is just like the two views on the right in Wayne's picture. Now I can't swear to originality of it, but I've owned for more 29+ years now and I've never had work done.

My car is an Early '64 (Nov 63)

Does anyone know what year or this style is from?

Re: 63 alternator boot

Here is a interesting picture from late 63 Z06 car and I think Rick Aleshire probably knows the serial #. If you look, the later style insulator is used but the boot is falling off some. Could it be the new boot did not start until64 harness #.

David;

Mine is like yours (thick web). Mine is a one owner 63 with a July 63 build, and I'd like to believe mine was untouched in that area.

That's probably a mid production car (alt wiring in lower position) so I would guess that the alt originally had the typical 63 terminal insulator without the outer ridge.

The stator looks like it has an amber colored stator instead of black so my guess is it's been rebuilt at some point and may have received the later style insulator.

The same 63 only alternator wiring harness was used through the end of 63 production without a part number change so if the boot changed at some point, it had to be a mid production change without number change.

The 63 and 64 harnesses are NOT interchangeable. The 63 harness had to be used through the end of 63 production.

Tim, My late 63 had the identical boot as yours. Car 19426 or close to that number had a boot that was smooth on top with little mold numbers and the bottom part of a cross. Meaning just the horizontal and verticle leg.
My early March car with late Feb engine has opposite so to speak. Just like Jorjorians (etc) pics. So there appears to be 2 of 63 boots.
the new style boot did not start until some time in 64. I was thinking of doing an article but it would be very difficult and probably inaccurate. How about one of the posters here doing that article as I am not that camera savy.
With all these great posts we have now determined that the theory of one that fits all is not correct. Keep the pics coming gang. What we need is an idea of when Packard changed from the early 63 boot to the later style 63 boot and then when did they go onto the typical one with the complete cross. Thanx, John

Re: 63 alternator boot

Here's a known GM #2984033 boot. This boot is still available from GM. However, this particular boot is from a quite old package. I have no way of knowing exactly what year this was manufactured but, based upon the part description printing on the box, I would say it's likely from the mid 70's, at the latest. Keep in mind that the exact configuration of this part probably differed over the years, if not within a given year.

Joe -- that looks like the boot on my repro harness (the 5th boot in the pic, below the row of 4). So maybe the repro guys were using an available Delco item, although not the configuration of the C2 era. Was on a repro harness probably manufactured during '80's.
