You should be able to get a pair fairly cheap at a wrecking yard. You can reinforce them as I did mine by laying a strip of 10ga. on the top and bottom and stitch weld them after they have been blasted with sand. I blasted the arms and Metal Preped with #79 prep. then paint them or you could have them powder coated or spray on some under coating as it is all up to you on what you are going to do with the truck. I would also put in new bushings and new bolts, lock washers and nuts.
