Thanks for the ideas guys. I ended up buying a set off Craigslist, they are off a '59 GMC long bed. The GMC springs are quite a bit refined from the Chev springs. 7 leaf instead of 6, grease fittings on leafs and leafs are tapered at the ends. They look like they will fit my truck, the only thing I don't know is if the rear bolt will be the same diameter? Suspension King wanted $180 ea plus shipping for my truck....
