Its been a few days and see the post was hi jacked, but that's cool, if the thread helps others that's ok with me.
For my project, I've since removed original perches (12 degree up) and will re-install rear with new 2.00" perches and then will re-install and get a happy angle, 2 or 3 degree, then tack the perches, remove rear axle, and stagger weld the perches, then re-install.I'll then change out the UJoint on driveshaft for the 12 bolt rear acceptance. Drive Shaft length looks really good so far, but will determine when I re-install axle for tacking the perches.
