bolt holes for relocation brackets
I can built the brackets, no problem, but I'm not sure where to drill the holes. I've searched this topic, maybe I'll have better luck if someone can post up some measurements or more specifically, what they did

NO NO NO
Both spohn and BMR put theirs with the first hole 2” down and the second 3”, and both are just a few hundredths of an inch forward of the stock one (you’d have to measure a set installed to be sure, but I’m sure that no matter what they don’t go more then 1/8” forward.
If one of the holes puts the LCA pivot where it would be at stock ride height then that one should be in line with the original, and then the rest should be moved forward by the relative arc made by swinging the control arm down while keeping the axle in place… Simple trig, and to make it even easier the LCA’s on 3rd and 4th gens are 19-1/4” long pivot to pivot.
