Well I had to try something so here is my imitation of a CalTrac for my Dart. My bars are 20" long and 2.5" down from center of main leaf F&R. Heim joint at axle and poly bushing at frame end. Ive been using a snubber about 1.5" from the floor and the lack of up travel sucks. I feel this might be the lesser of 2 evils until I can fab up a 3 link/Watts setup. Here is a mock up pic with a Sharpie circle indicating where the leaf contact bolt will go give or take. First pic is full droop.
