i'm looking into buying a mustag with a 4cly/auto ad i was wondering how hard it wold be to change it over to 8cly/manuel ??

 

The motor swap isn't that bad, but going from an auto to a 5spd will require some work. You have to get the clutch pedal assembly up under the dash. But to do the job right, you need to change the suspension, guages, rear, and brakes. Quite a timely process.
