I used that leaf spring slider on the 69 Dart for a couple summers now with zero issues on the rear. Never seen or heard of anyone using it here and was just looking for some input.
As for the other thing we talked about...I'm going to keep a lid on that until I pull the trigger...IF I pull the trigger... work
I mapped out an area on the front rails near where the front hangers for the springs are for a bar to tie in from the frame back to the roll cage. This will give me a good point for the shock bracket at the top.
I did a few small modifications to the front spring hangers tonight and will post pics once I get them loaded Thursday.

...FAFO...
