I would find some left at a loading dock (load bars)and ask if I could have them. Then after you get them, use a 1/2" drill bit and drill the end of the rivet out holding the stud in place the holds the end assembly in the bar.Then cut the bar a little shorter than what you want, and use a 3 -1/2" long bolt x 1'2" thick to hold the bar in place. This whole ordeal will take less than 5 minutes to do.And it is cheap.SAVE THAT MONEY!!!!!
