I just recently completed replacing a trashed 4-speed with a rebuilt one. Same Muncie wide ratio.
The previous owner installed the transmission crossmember wrong resulting in the trashed transmission and concaved wear on the driveshaft yolk.
I replaced the yolk with a similar dimensioned new one. However, with the crossmember properly attached to the top of the chassis flange, the
exposed portion of the yolk tube is greater than before. The bad yolk had about 1 1/4" of the tube exposed between the transmission and the
universal joints. It now is over 2". The total yolk tube length is 3 1/2".
I can't tell if the old owner shortened the driveshaft or what. Does anyone know the correct total length of the driveshaft (tube only) and the exposed
portion of the front yolk? I noticed there is a yolk available that is 1" lnger than the one I have.
Thanks
