    I swapped a 5 speed out of a 1991 pickup into my 1975 pickup. I used the tailshaft slip yolk from the 91, but the u-joint is larger than the one on the 75 drive shaft. Is there a conversion joint I can use?
    1” to 1.1375”
    Thanks, Tom

    Second a driveline shop. You might have to have a new driveshaft fabricated if there are no available adapters to modify your existing shaft.

    I had to do this when I installed a GM 14 bolt rear axle on my motorhome.

    There is no conversion joint available, I contacted Moog. I am having to change the end of the driveshaft to the larger yolk. Oh well.......typical for me..........

    Swapped the end of the driveshaft and it bolted right up. Had to redo the trans mount, trim the floor opening slightly, shorten the clutch slave cylinder rod 1/2" and added a B&M T handle shift handle for ALL the extra horsepower.
