Been working on adding some truck bars and coil spring rear suspension to my 1980 square body. in an effort to get a better ride and hopefully some better handling I took an old 72 rear end and suspension and adapted it to my square body. I have not been able to find much information out there on how to accomplish this, but this is what I have accomplished so far. Hopping that some of you guys that are much more accomplished on suspension than I am will chime in. located axle position on frame prior to disassembly Removed rear end and leaf springs added entire rear end, truck bars, and cross member to square body frame in original axle position. installed cross member with brackets up and truck bars contacted frame before axle did when I moved it thru full travel, also had drive shaft clearance issues along with cab. installed cross member with brackets down like factory, truck bars still contacted frame before axle did (still had all the same clearance issues) On my third try I dropped the cross member down 2.5 inches. This corrected all of my clearance issues and where it gets fuzzy for me. Do I have enough ant-squat? The bars have a 5 degree up angle on them at ride height. Is this enough, how much higher should the front mounting point be than the rear?
