Carter AVS Rebuild Kit

Does anyone know where I can find a rebuild kit for the Carter AVS 4226S. I know they were bought by Edelbrock, just wondering If I can just ask them for the kit or if there's another way to go.

Also, I've heard of a strip kit for the Carters that used to be around. Can anyone give any insight as to what that is and if it might be worth it on a 383.
