What are you guys doing to ditch the wimpy 47" springs?
Looking at the leaf spring chart it looks like the 131" WB FSJ rear springs would be a good setup up front.
Relocation of the rear hanger and possible retention of the stock front hanger with longer shackles to get the angle where it needs to be?
I have old 6" BJs lift setup SOA on my J20, the front springs are whopped out (flat) looking for longer leafs to give better life, ride and flex.
Measurements:
Stock FSJ front 22.5 x 24.5 = 47"
131" WB FSJ rear 25.250 x 31.75 = 57"
The 31.75 end would go to the relocated rear hanger.
