I have put a 2.0 with a c4 automatic in a 31 Ford .I would like to put a 5 speed stick in the 31, will a trans from a 1980's 2.3 Mustang fit? All the Pintos Capris & Mustang IIs are long gone in the local junk yards . will I need to have the crankshaft machined for a pilot bushing .Thanks for any help
