Replacement brackets?

[mr.miyagi]

Hello, I'm completely modding my cobalt flux with arcade sensors, ddr panels, and the likes.
However, I'm not sure where I could get the metal brackets to hold the arrow in place (the ones in the 4 corners of the arrow)?
If not, any suggestions as to a good triangle bracket places that may sell something of the likes, like Lowes or Home depot?
(like these... but without the constraint of selling 32 at a time..!)
Corner Metals for DDR Floor Arrows - Dance / Music Machine Parts - Spare Parts - Arcade Video Game Coinop Sales - Coinopexpress

Also, would any standard L-bracket work for this method or would I be able to just find any sort of L-bracket that looks similar that may work?
Thanks a ton... <3

Channelbeat sells them, but they normally require orders of $100 or more
