When removing my gas tank and prepping it for repair I noticed what appears to be a discrepancy regarding my anti-squeak pads; at least from what I have found when looking for replacements pads in the parts catalogs. The tank pad closest to the sending unit was only 2" wide, while the one closest to the "A" logo was 3" width. However, I have only been able to find 3" wide pads in the catalogs. Further, there were no anti-squeak pads under the two tank straps. Could they have just worn away, or were they left off sometimes? Finally, does it make any difference what type glue I use for the new pads? It looks like the old glue was a tan-colored product, which was applied rather haphazardly. I am almost 100% positive that the tank has never been removed, but there is always that 1%. Any advice is appreciated!

Re: 69 Tank Anti-Squeak Pads
Sounds like the strap pad are gone. I believe they should be there. Both strap pads were the same width as far as I am concerned. They have the same part number as I recall??

No pads were used under the straps. The AIM calls for none and my original-owner 69 never had them.
The anti-squeak pads were of different width. You can either trim one of the vendor-supplied pads to that width or you can just use them as-is.
The adhesive used to afix the pads was a neoprene solvent cement. Originally, it was yellow, but it darkens to brown with age. 3M Super Weatherstrip cement is virtually the same product as was originally used. It's very easy to find, too.In Appreciation of John HinckleyComment

Re: 69 Tank Anti-Squeak Pads
Save your money on repro pads. The originals were made of a rather thick felt material (approximately .100 thick) while the stuff being sold is only good old tar paper ( approximately .020 Thick)...
Visit your local roofing company or job site for some scraps....and make your own.
The widths on mine were 2" on the front; Part #3763913
1.5" on the rear; Part #s 3828635 (long piece) 2ea #3785850 (short pieces)
The above mentioned original material is from a 67... more than likely the same as a 69....Check your AIM

Re: 69 Tank Anti-Squeak Pads
Interesting. I have had some original tank straps out of 68 corvettes and they have the black tare paper stuff attached to them (very deteriorated of course). The other thing is that the 68 assembly manual describeds the tank straps as an assembly 3923691. I also know that good Dr. Rebuild sells them for the straps. I wonder if this is a variation of some sort?
Take care, TerryComment

Re: 69 Tank Anti-Squeak Pads
Because of the thickness issue, you can take tar paper and simply double or triple layer it to get the right thickness. A little heat, and it will all merge as one.
My June-built '68 had the tar strips both under the tank and under the straps.Comment

Re: 69 Tank Anti-Squeak Pads

The straps were comprised of a steel stap + weld nut + (as I recall) a welded-on reinforcement. In GM parlance, that makes them an assembly. Also, the GM #3923691 strap assemblies were once available in SERVICE under the same part number as the PRODUCTION part. They did not have any sort of "padding" or "anti-squeak" as a component thereof.
It may be that the factory added anti-squeak for all or part of the 1968 model year. They could easily have improvised such parts by using pieces of the anti-squeak used for beaneath the tank. I don't know why they would have done this since it's not specified in the AIM and, as far as I know, earlier Corvettes never used padding under the straps, either. But, they may have done it for some unknown reason. I know, for sure, that my 69 never had it.In Appreciation of John HinckleyComment

Re: 69 Tank Anti-Squeak Pads
Sort of weird. The set I looked at in my garage have that asphaltic pad and it is glued down by what appears to be that rubber cement. It is pretty brown now. I wonder if Dear Dr. Rebuild has an opinion. He sells them for the straps??
Have a great weekend! TerryComment
