Where can I get that super wide chinup bar attatchment made by Joe Gold that Arnie used that is shown in this month's Flex magazine? I tried looking on the net and I could not find one like it at all. If anyone knows where I can buy this, please let me know.

I'd go to a welder and have him make me one....
