lets get back on the subject here, i fabricated my long arm kit out of the choped up remains of a teraflex tj lift kit. i took the threadad side of the LCA's and cut them about half way between the thread and the bushing then i welded them in the tubing, i used 2x2x1/4"wall square tube placed to look like a diamond. you need to figure the desired length you need, i needed to move my axle forward so i went longer than most, my long arms are 36" hole to hole with outward adjustment from there, but i pushed the frame side back too to give me the axle positioning i need. i need to get a digital camera and do a full wright up on it because i did the cross member and trany mount combo and the UCA's are welded to the LCA's and they are choped and modded pieces too. ( a total PITA but i loved it )
well good luck on your project.
