Re: d21 71c questions

If you change the bell housing it will still remain the same length. The bellhousing is literally the same except in some cases the ribbing is more extensive and the front countershaft bearing is larger (should be 62mm.) The shortest FS5W71C transmissions are in the D21 if I remember correctly. The "C" trans is a marked improvement in reliability over the "B" trans, though many inner components appear the same. In basic "C" form you get a double cone syncronizer on 2nd gear, wider gears and a stronger input to countershaft setup, as well as an improved shift mechanism. These are big changes that make this transmission much better.
