No but that would work. Most racks come with 2 long stays where the end is bent 90 degrees to the rest of the stay. You can use a vise to straighten these out but like I said it ain't purty. Your two pieces of metal there would probably work better anyway. In a pinch, I suppose you could use the flat metal stock that is used on chainlink fences to tighten them, although I think I'd see what the bike shop has first.
[Edit] Make sure you use 2 bolts to keep the whole thing from rotating. A nice 10-32 cap head bolt would work.
