It may be cheaper to get your own fabricated if you know of someone with a set to hand, theres really nothing to them that a machinist couldn't handle. You could alter the ends so you wouldn't need end caps - i always feel these look crap! Wonder if you could use aluminium?? I'm looking into nickel plating for mine! Its said to be a more subtle and desirable finish - not as shiny as chrome. Sky's the limit mate!
