63 Powerglide

[Bob R.]

I have just installed an original powerglide in my 63. The installation went well until I tried to install the flywheel cover I had purchased. It didn't fit. Does any know where I can get a powerglide fly wheel cover? I've searched several sources and so far no luck.
Thanks for the assistance,

It depends what you're after. If you want an original cover, that piece was GM #3789959. It's been discontinued for well over 25 years. However, it's not a rare item in the used parts market. It was used on all manner of Powerglides from 1962 to 1968. All you need to do is locate a 62-68 with Powerglide Chevrolet in a wrecking yard, and you'll likely have what you need. Many wrecking yards might even have this piece in stock, already "pulled" from the car. I'll bet that they don't sell a lot of them these days.

If you don't care about complete originality, a replacement underpan is still available from GM parts. If you go in and ask someone at a Chevrolet dealer for an underpan for your 63 Corvette with Powerglide, they'll likely tell you that it is "discontinued". But, it's NOT. A 1969-era replacement is still available from GM. It's GM #3933089. I don't know how this pan differs from the original, but it should be a functional replacement.
