It has been years.........and cant remember what is needed.
I have a 30k trans from a 99 Grand Prix Gt.
I want to make it a 2.93 HD trans for my 02 regal Gs.
I have the 500hp input shaft and gxp chains to bandaid it for a bit.
Do I just need to swap my regal diff, output and cover to it? Or were the sprockets needed too?
