The only holes that line up with my stock pan are the rear main studs. All the others are no where near close, you can't even see any of the holes. Really baffled me why GM would change the pattern.
The good news is its a pretty simple mod to the aluminum pan to make it work. We just have to grind off a trans line mounting lug and a couple of fins to make a room for the turbo return line fitting. When we get it done I will post some pics of it.
