rcv axles w/ the wj knuckle swap ? anyone tried this yet, the clearance for the boot is extremely tight even after the grinding has been done on the xj knuckle. does the wj knuckle sit even farther back on the inside towards the end of the axle tube ?which is why the other side is spaced out 1/4" to index the outer stub & u joint properly. which would mean machining the wj knuckle in maybe a 1/2 " so the boot will clear the bolt heads that attach the unit bearing ? is that even doable ? just thinking out loud here, any thoughts.
