Hi guys. First post here, tried the search but didn't find anything. I have an 87 base model that I'll be doing a 3800 swap on and trying to decide on transmission. I have the 5 speed Izusu but I'm thinking F23. Is there much difference from the M86 to the M94? Also I'd like to confirm that it would be a 2000 to 2002 Cavalier I'd be taking that transmission out of, correct?
