GM OD tranny fit?

ok well this thread seems to have tailspinned. all i wanted to know if if it was easier to fit s GM tranny in because i THOUGH (key word) that i read somewhere some1 did it. i never sed "i say the GM tranny is better"

it looks like im not goin with either a GM or the 518 for the time being, since i h=dnt have the tools or expertise to do the convertion. id rather do the 518 since its a mopar tranny. id hate to use a GM tranny because id have to hide it from my Chevy buddy, but for some reason i thought i saw it somewhere

My apologies for going sideways on your thread. This actually does have the potential for alot of usefull info. All of these swaps have been done before and those that know can supply real good advice.
