was up Iam putting on a 5inch lift from all pro got the front done .Started the rear, need alot of info on finding the pinion angle so I could weld the leafspring perch on.I know you have to use a angle gauge finder but how many degree is it safe to move the pinion up?Oh its a 85toy pickup x-cab, not planning on runinng duel case for awhile,but will be putting on 37inch tires.
