Thank you. Simple made it easy to do. It feels like the rear rides much better now. Could be placebo effect, the shocks are a little bit more angled. I'll probably add acorn nuts to the ends to protect the threads of the bolt.
I decided to make the rear shocks high clearance. So I built these
I whittled them out of 2x4 .25" wall.
9/16 grade 8 bolt
I was amazed how easy the old mounts came off. I cut about a 1/8" into the weld and knocked them off. Then I cleaned up the tubes and tacked the new ones in place.
