Bellhousing

Can anyone tell me. Does it really matter with the bellhousing used to put a 4 speed in a 67A body if I’m not trying to be year exact? Thanks

67 to 76 A body 4 speed conversions are pretty easy. If you are lucky it will cost you about $3,000 for factory setup including a rebuilt trans by the time you add in a 4 speed shifter, clutch pedals plus linkage, and trans tunnel. You will also need a longer driveshaft. Pick or find a 10.5 A body bell housing and match the components from there.

You can do it cheaper, but the process is the same. Good luck.
