Im in the middle of swaping out the auto for a 5 speed, after taking a few measurements it looks like the rear driveshaft is going to be short and the front to long. Does anyone have any input on the legnth I need or have one for sale. (Its the 94 F250 in my signature) Or is it best to just take it to a driveline shop. I just finished installing a factory turbo now the zf, mabe it'll wake this ol' girl up.
