Picked up my original front sections from the shop. Got them installed. With a 6* shim i now have 4* pinion to shaft angle. Gained some tire clearance, but now may need a new drive shaft. The slip yoke is 1.75" from being all the way into the tail shaft. Didnt measure the yoke, but i would guess its 6 or 7" long where it goes into the tail shaft. That still gives me 4-5" of sline contact. Enough?
