Questions about flipped springs

[BenZZilla]

I just put some 4 inch rough country springs in the rear of my '72 and I flipped the springs 180 degrees my question is what did you guys use for shims, to rotate the pinion back up. I bought my springs used so there were no shims to begin with. any help is appriciated

bolt everything temporarily , let it stand on the ground and with an angle finder compare tc output and diff output , you want them paralel

No springs come with castor shims. You may find that you need them but they would need to be purchased separately. The only time I have needed them is when using longer than stock shackles. However a really lifted spring can do the same thing.

ok thank you I was just hoping to here from someone who did it themselves so I could work out a few other issues. I will give that a try

I'm curious why you mounted the springs backwards? If it was to lengthen your wheel base I think there are better options because the springs were not designed to carry your load properly with them mounted backwards.
