I thought about it, but making the holes is a challenge. Punches are available but $$$$.

Re: Source for correct foam idler arm seal (1971)?

The 71 I’m working on has a new restoration idler arm. It comes with a rubber seal that is at least 3x thicker and 10x stiffer than the original foam-type seal. The owner still has the clear plastic piece from his original.

Does anyone know of a source for a correct foam (non-rubber) idler arm seal for a 71? Doc Rebuild has them, but he is closed indefinitely due to COVID. The other usual sources seem to all sell a rubber seal, which just isn’t correct.

I’d appreciate any suggestions you many have.
I did think of making one, but buying the tools to cut the outer and inner surfaces cost far more than the part.

Thanks.

If it's a one-time need, you could make the hole punches from short sections of hardware store pipe of the appropriate diameters. Sharpen the end of the pipe to an edge and use it like a punch.

Patrick,

Give me a call and I'll give you the number of the one who has those made! (in China).
