I have it up on its rear wheels now. Full suspension compression (as in no coil overs installed. ) I drew in the locator bar design. It goes to the pinion snubber bolts , one bar per side, and connects to brackets I built on the ladder bars. Trans and diff line up perfectly (how'd that happen?) I will find the average angle and then glue it together permently. I figured absolute max rear spring compression at 4 inch with no more then 3 inches under 99% of circumstances. The tires look like they will clear. These are just some old push arounds borrowed from Mike and have a huge offset but it looks like all will be well. Car will have a bit of a wide stance and I would like to keep front and rear same averaged track. (55 inch currently for both.) It looks like it will work with the right wheel choices. Ride height is about the same as my 63 Dodge and my slant six FED allowing for the 4 inch spring rise. That is measured from the frame to ground.
This is getting to be a very interesting project for me.
