Asking $150 for everything including the proportioning valve. They are from a 68 heavy F250. I got a rolling chassis for the rear springs, mine are destroyed. I'm keeping the whole rear end as it has the same ratio and giant brakes. I'll see if I can get pics soon.
1 5/8 x 3, standard size. Radius arms are available too, it's all still under the chassis. I'm going to pull the beams next week for myself, if nobody wants anything else then the rest is going to scrap.
