I'm doing a D60/D70 swap from a 92 W250 Cummins truck into a 74 Ramcharger.

The rear I'm having a new driveshaft made so due to the 1410 Yoke requiring a 3.5" tube.

On the front. I'm able to wrestle the front shaft on by fully compressing the slip joint, but this leaves NO room for the suspension to travel and further compress the slip joint which will obviously be an issue.


I know that the D60 has a longer pinion length than the D44, bu how much I don't know, but how do I know how much to have the shop cut down my driveshaft? Do I just take a SWAG and call it 1.5"?


(SWAG = Scientific wild a$$ guess)
