Ok guys i need help here. Since the CALMINI 3" S/L is nearly $1k last year I decided to ebay the parts. I got the back suspension off ebay for $200 and jsut got my UCAs in today...next week I hope to get the Torsion bars in. The guy I ebayed the back suspension from didnt give me the u bolts, center bolts for the aals and i dont have the metal sleeves for the shackles. Ok when i order my torsion bars and u bolts on thursday i was gonna go pick up some bolts to act as center bolts....what are the dimensions that i should be looking for...need nuts bolts and washers i would assume? and are the metal sleeves that come with the shackles terribly important? i ahve looked around and no auot parts store or hardware store have anyhting remotely close to anything replaceable for those damn sleeves.
