Ok I have posted the want for a used diff. assy. but so far no takers. The truck is taking up much needed space so I reversed the springs, slid the axle forward about 4 inches and then lifted the diff. assy. so that the torque tube is in a straight line with the transmission and made sure I gave the shaft clearance at maximum extension. Then I lowered the diff. onto the springs taking care that the clearance increased as the diff. lowered. the locating pin is 1 and 7/8 inches forward of the hole in the axle mounting. I intend to build a mounting pin relocator from a 1/4 x 1 3/4 x 4 3/4 inch flat bar and allen head bolt or a 1/2 inch dowel. This should give me the clearance and put the axle forward about 4 inches (much better than before). Still looking for a diff. assy. but the truck is out the way. http://i1070.photobucket.com/albums/u497/toyvo75/Untitled_zpsjlz6ymjq.jpg
Anybody see why this wont work? The shaded area is where axle perch will be.I don't have a drafting program and did this in paint. So it is not to scale.

I didn't do it, no one saw me do it, you can't prove anything! "Bart Simpson"
