I have to make my own shackles for my ORD flip with ford 57" springs. My K5 was my daily driver, but now it's my weekend driver/road tripper. I wheel mostly ttrails and skid roads. I have both 1/4" and 3/8" by 2" flat bar. Is 1/4" beefy enough if I weld a brace between the two sides of the shackle? I could go with 3/8" but it will be MUCH harder to bend, seeing as how my only torch is a MAPP gas torch. Anyway, is 1/4" enough, the ORD brackets are made of 1/4". Or, should I play it safe(r) and try with the 3/8"?
