Oh, sorry. Looks good then. I know you designed this to fit the supershifter gearbox, but it might be easier to make if you used 4" tall sides instead of 5".

With 5" sides, you would need to order plate and cut it to length and width.

With 4" sides, you can just purchase 4"x3/16" Extruded Flat Bar and cut it to length.

I guess if your gonna CNC or waterjet them anyways, it isn't that big of a deal, but I'm pretty sure flat bar is cheaper than plate anyways. (I can not find 5"x3/16" extrusion anywhere).
