Called Eaton Springs and talked with Kim today. Found out the missing spring bushings were the rear hanger bushings, which fortunately Sacramento Vintage Ford has. The guy at S.V.F. was super helpfull. He invited me to visit their 17,000 square foot show room. It would be like going to the candy store for me! They also have a bed conversion kit there. 1948's had a wood subfloor on the pickup bed, with a metal top pan. All of that was missing from mine when I got it, so trying to figure out what to buy and where it goes is a bit confusing, and very expensive. The wood floor conversion kit is a bargain, since it takes care of using a metal floor, with wood subfloor, and just replaces everything with 5 oak wood panels, and stainless steel strips. Time to save some more pennies, even though I don't need the floor for a long time yet!
Well soon as the hanger bushings get here I can start on replacing the rear springs. As Dave say's waiting on the Brown Truck!
