Door Handle Gasket Con't.

[Rey S.]

I have been researching all of my catalogs and the AIM and I finally found a reference to the gasket under the door handles for a
C-3. Many of you have been claiming a gasket from the factory, many claiming no gasket from the factory, well in the AIM in section 10-46, pn #28 is a seal that goes under the door handle assembly. So I am now under the assumption that the factory did in fact install some form of gasket/seal under the door handles.
Thanks for all the input on this matter.

Through 1977 the AIM's show the seal. Whether they were actually installed after 1974, I do not know. From 1978 to 1982 no seal is shown.

The GM #3956022 was used from late 1969 through 1977. It was discontinued from SERVICE without supersession in 1977.

The GM #3918560 was used from 1968 through early 1969. It was discontinued from SERVICE sometime after 2002.

I do not know how the above two differ. However, it's curious that the later part was discontinued in 1977 and not replaced for SERVICE by the earlier part which remained available for at least 25 more years. Apparently, for whatever reason, GM did not consider the 3918560 as a suitable replacement for the 3956022. Seems strange to me.

Hello Michael
The AIM (?) I use is 53 thru 82 Parts & Illustration Catalog, effective 12/83, GMC 14A. It is aprox. 2 &1/4" thick. The first half is nothing but Part numbers, second half is all the good stuff. I found this book in new condition, wrapped in clear plastic at the Pomona Ca. Swap Meet a number of years ago. I have 2 AIM repo's from NCRS. The information supplied seems for the most part to be the same the only difference being my book has a bit more detail in regards to part numbers.

Rey,
That's not an AIM, it's a P & A catalog, and has to be understood to be used. Those were issued annually. Then quarterly. There a number of errors in descriptions. Also, GM would gather together several original parts and use one part that would fit/function okay. The 56-62 hood release assembly, e.g., was incorrect from at least 1973 on.
There are parts supercession manuals and parts discontinued manuals with dates of discontinuation and supercession given that you need to reference.
Relying on the manual you are using would probably be less accurate than relying on the illustrations in the real AIMs.
You need every Chevrolet P & A issued from 1972-to the one you have to determine if the one you have is at least reasonably accurate. I'm guessing that the illustration sheets you refer to in yours are a green shade.

The GM #3956022 seal that was used from L1969 to 1977 won't even be included in the P&A catalog you have since it was discontinued without supersession in 1977. The only seal that will be included in your catalog will be the GM #3918560 and it's only cataloged for 1968-69.

As I mentioned previously, I can't imagine there was much difference between the two aforementioned seals but there had to be some difference.

Re: Door Handle Gasket Con't.

The 68 door handle gasket is shaped differently than the 69-later gasket due to difference in shape of the handle itself. One is more rectangular while one is more "twinkie" shaped. I'm gonna assume thats why GM didn't consider the gaskets to be interchangeable.

Hi Mike
Thank you for the corrections to my post about what I have been using for an AIM. I perhaps should do more research in the future. I am just
home garage hobbyist so I don't always take the time to research things as I should.
Thanks again.
P.S. The pages are shaded green

Rey,
No problem. I'm only a hobbyist too. In real life I've been a clergyman for 40+ years. We all learn along the way. My post was designed to be helpful and informational. I hope it came across that way.

Re: Door Handle Gasket Con't.

Just went to garage and looked at '78 my Dad and I ordered. Cannot feel or see a gasket. My '77 I ordered is away from house but has original (cracked) gaskets
