would a c4 transmission out of a mustang be longer than out of a f-150? supposedly someone put in a mustang c4 tranny but the driveshaft literally has no room to move, it is AGAINST the tailshaft. I just want to know what the factory tranny was so I can put one back in. that or upgrade to c6 and have driveshaft work done...
