I have to create new mounts from scratch for a triangulated 4-link rear suspension on 32 Ford rails for a 9-inch Ford housing. Does anyone have specifications for this setup, such as recommended control rod lengths (upper vs. lower), and especially the angle of the upper rods? Also, should the rods be parallel to each other (and the ground)?

I have decent fabrication skills, and I want to avoid buying mounting plates if I can, but if that will be cheaper in the long run, I could do that. I am using pre-fab control rods and adjusters with urethane bushings, it's just the mounts I want to fabricate.

Thanks for any help.
