looking for a 429 heat riser and cruise control unit

I am looking for a functioning heat riser valve and a cruise control for a 1964 Cadillac.

In principle, the heat riser flap does not have to work. It is only important that the spacer / housing is not broken or has a crack.

Cruise control does not have to work 100% either. The shaft bushings must not be knocked out.

Does anyone have something like that lying around?

Here's an idea for the spacer: I don't know if you have access to a machine shop. Luckily for me, my neighbor is a machinist and made a spacer out of scrap metal when my heat riser cracked. He tried welding the heat riser first but he did not like the result. The spacer fits perfectly and the exhaust has been leak-free for about 10 years now. Here is a picture of the spacer & old heat riser:

1963 RHS A/C kick panel - photos needed

Posted by SK on June 2, 2025 at 2:20pm 2 Comments 0 Likes

Could someone post front and back photos of the 1963 right-hand kick panel with A/C?

My car didn’t come with the original kick panels, so it's a bit of a mystery to me how I should cut the backing board and carpet to fit around the A/C.

Many thanks,
