Chip, you can take the busted bar back to HF and get another one (or maybe your money back?). I recognize the design of it...got one just like it.
A note about removing stuck fasteners: The way you finally got that bolt out is the right way to loosen almost any stuck fastener. As long as the wrench fits tightly, a quick snap with as much force as you can muster works a lot better than an extended pull.
