Hotchkiss or Helwig rear sway bar?

My experience with Addco bars on a few cars now has been that while the bars themselves are decent, the hardware leaves a little to be desired. Generally Addco just ships a bunch of miscellaneous universal brackets and hardware. It works, but you end up with something that looks like an Erector set, flexes and loosens up over time. A few well placed tack welds help, but it's a PITA. It looks like Helwig, Firm Feel and Hotchkiss use better thought out OEM style mounting brackets, which is probably the best way to go.

I bought my Addco early-A bars before Helwig and Hotchkis had theirs on the market. They're still new in the boxes. Anybody wanna trade?
