You sure those silver colored ones are not aluminum?These are one-off specials. However, with the pictures I have posted (and the additional pictures that I have in my possession) any good fabricator should be able to duplicate them.
The ones on the TUV's are made of stainless, apparently, wihch is overkill in my case. I would just need steel, painted grey. Any good welders/pipe benders out there? Maybe a Millwright or two?
Great idea, though. I think a guy could obtain an already made ATV rack and modify it to fit. Sounds like a good project.
