i have a 67 ...air ride with c-notch in back and 2.5 inch drop spindles in front.. i like 20s but would like to go 22's..i've looked at a few trucks that have 22's that slightly tuck though im not sure of the mods they've done.. so could i tuck 22s even slightly or should i go 20/22 or just 20s all around..thanks
