I have a 3 speed standard v6 car that i bought as a parts car. It is complete. if i do the swap Can i bolt a 4 speed M21 right up in there using evrything from the 3 speed swap, crossmember and linkages? Any pointers on doing the swap??? any hints that will make it go more smothly. Anyone interested in the 3 speed trans ???? are the bell housing from the v6 same as v8? will the 3 speed bolt up to the v8 if i decied to keep the 3 speed Thanks
