How do you usually narrow a rear? I did my first one 2 weekends ago, ford 8.8. We did the math to get the axle tubes the right length we wanted (its an offset dif) then put it on the chop box. made out cuts, beveled and then used 2 pieces of C channel and clamped them together nice and tight to keep it aligned. Tacked it then tacked on some 1/4" plate in 4 places around it standing up to make gussets so heat didnt warp it. Just would like to know how you pull it off and compare strategies.
