I havent heard of anyone using a 2g auto in a csm.. I have a 1g and it barely fits... with a 2g you need the adapter kit and I think that will make it not fit unless you cut and rebuild the pass side frame rail.
same with a 1g dsm.. not many.(if any) have put a 2g trans in cause of fitment issues... people do put a 6 bolt into a 2g but need that adapter kit for it to work.. and if I recall the 2g width is 1" wider than the 1g.
if u got a good deal.. you could get it..resale it and get 1g stuff and make some money lol..
Lol well with my current setup I will be destroying 5-speeds, & this isn't one of those deals you pass up really. Its a built to the tilt trans, & converter. I am thinking about getting it & just doing some fab work. But getting the trans to fit is only half the battle, next comes the axles.
