" From: Jesse <j2sax@xxxxxxxxx> " " So I have the TH400 adapter from a 72 Commando and I " want to use a RWD OD tranny behind a 360. Are there " any close to bolt ons? I prefer manual, but Auto's " will go for this. hmmm. the only gm th400 adapter i know of fit the buick nailhead case - which jeep used '65-'73 or so - to the '69-'71 buick 350. you could use it to swap engines but it wouldn't help swapping trannies. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
