I swapped a chevy 12 bolt rear91969) into my 1950 3600. The rear axle angle is 12 degrees up. Has anyone experienced this amount of angle before? Can shims fix 12 degrees or must perches be modified? Based on the rear driveshaft, i think if i can get rear axle to about 0 degree, that would give me about 3-4 degree pinion angle, in the end. Any thoughts, experiences?
