I suppose it wouldn't be too hard to copy one with a sturdily mounted metal brake. The alternative would be to just weld something up instead of bending the metal. That was my alternate plan if I failed to find these.
I appologise for the quality of the pics. I've gotten lazy having this iPhone camera now.
Approx 1-1/4" thick, approx 3/16" thick metal.
17" Across from mounting hole to mounting hole:
13-1/4" Deep
3-1/2" Between Mounting Holes
If there is anything else, please feel free.
