And get under the truck and check the condition of the frame and crossmembers before you lay down your hard earned money.
They love to rust through near the gas tank, and where the crossmembers attach to the side rails, especially towards the rear of the truck, and where the spring brackets are riveted to the frame rails (both ends of all 4 springs). Rusted frame pieces are hard to fix and expensive, money is well spent on a frame that is in the best condition possible. I know because this is the kind of work I do. Gene
