SPC ADJ Control Arms

I just ordered a set of these for my 72 DEMON so what you are both saying is remove 3/16 of an inch off of both ends of sleeve and an additional 3/16 off of each end of the threaded rods on the rear arm of the control arm. Ok I get that but that being said did you have to do both pass & driver sides also how about the fronts did you need longer ( or shorted) sleeves or were the standard 4 inch ones good ???????
