i have a 85 xcab with rears up front (some lift spring leafs added). total 3 to 4 inches lift. with factory front hangers and boomerang shackles. I had to turn down my factory front spring pins in order to fit into the spring bushing steel sleeve from the rear spring.. i dont know if this is how everyone does it but it seamed to be the best way. (it was expensive because the pin was hardened and i had to have it annealed and then re hardened after turning it down).
i also had to use 2 degree pinion shim to keep my steering angle as close to stock.
i have been driving it for 2 years now and it has served me well. the tierod and draglink does bind a little on the spring at full lock on flat ground but not when stuffing a tire surprisingly.
so now that you understand my setup, i want to get rid of the shims and add a front spring hanger. can i use a common one from marlin or allpro and be able to use it with my ruf's my main concern is the spring bushing at the front hanger and the bolt size. i think they are 19mm and the rears are 18mm sleeve. i tried finding bushings to Fit my springs and a 18 mm pin but that was impossible. also will i get enough drop to cancel out the need for the pinon shim with the marlin or all pro? i did see but i forget where, a custom front hanger with a longer drop. it looked flimsy but I'm sure it can be beefed up.
thanks for the help. i did research this quite a bit but have not found anything usefull.
