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.
Well besides cutting it out and welding clean sheet metal in, fiberglass is really your only option. Fiberglass doesn't absorb moisture like poly filler does. You're ok, but you might want to drop the head liner down and see what's under there.
I started on the passenger side swing out. I'm using the same size bushing as the tire swing out, the main beam is slightly smaller square tube. I'm still getting my welder dialed in but my welds are looking much better.
