    Those of you running 70s out back what are you using for spring plates and u-bolts? U bolts aren't so much the problem, I don't want to make spring plates.

    thanks,
    Thor

    I am running my old 14bolt spring plates w/ the holes hogged out a touch, and I got my ubolts bent up at that spring shop in Auburn/Kent right off of HWY 167... was under 40 bucks for 4 ubolts w/ washers and nuts.

    3 1/2" axle tube, same as a 14 bolt. The 14 bolt FF's use the under the axle spring plate, but the 14 bolt SF equiped trucks used the spring plate on top of the springs. The SF spring plates will fit your D70.

    Blue Torch Fab makes real nice spring plates (with the bent ends, like OE). I asked about making some for the 4" tubes and they said no problem, seems like they quotes somewhere around $45~$50.
