My recipe was a 550lb front spring, 1 1/4" factory front sway bar, rear factory 5/8 sway bar and stock TA rear springs. I have steel lower control arm bushings I made Delrin spacers to take up the slack and Herb Adams upper solid control arm bushings I converted from weld in to press in. Sapping the lowers out now for Global's Del a lum bushings. I had poly shackle bushings but they are prone to binding and popping. Drag spring had a solid aluminum front spring eye bushing. Global has a spherical bushing for the front so it can articulate some as leafs actually do rotate. I prefer Global's interlocking solid subframe to body bushings. Bilstein's all the way around. Still felt "softer" than the 1985 full sized Bronco I had with stock suspension.
On the 81 TA I used upper and lower A arms from Global. a stiffer 750 lb front spring I had used on the Camaro when I autocrossed it and the SBC in it. You can do the 1LE 12" rotor B body spindle swap. I have that on the 81 but it has not had much driving since all those modes. There are Vette 13" rotor kits that require a 17" wheel if going that big.
