According to OReilly's:
Gates XL V-Belt 3/8 Inch x 53-5/16 Inch - 7525
Part #:7525 Fits Cadillac DeVille V-Belt Fan And Alternator; With Air Conditioning

I ordered a full set of belts a couple of years ago from Amazon for about 1/3 the price as the same belts at auto parts stores.

Thank you, Kurt, much appreciated. Auto parts stores prices have just gotten ridiculous. Just bought the fuel hoses from the tank, O' Reilly's charged about $5 a foot for 1/4"and 5/16" fuel hose!

Gates 7525 is what I have noted for AC cars. 7530 is what I have listed for the non-AC cars. It is slightly longer (53 13/16"long) to accommodate the wider 2 groove water pump pulley used on non-AC cars.

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,

Edelbrock Carb Block off Plates

Hey guys,

I have installed the same Edelbrock carb and have done everything the same as Jason’s carb and intake project. In the spring and summer months the car starts, runs and idles great! In the fall and winter months on a cold start, the car starts awful and wants to die until it warms up. I have to keep my foot on the throttle until it warms up or it will idle just terrible and try to die. Once it’s warm, it runs fantastic! Whats going on here? I was thinking of removing the…
