RTMR Mounting Plate - Source

I would like to install and RTMR with mini busbars on each side and a mini-breaker. I have a 2022 automatic so I can mount it easily under the hood using the two existing threaded holes in the fender.

I e-mailed Yotamac and inquired but got no response. So I assume he is no longer a source for the pre-made mounting plate which looked to be exactly what I needed.

Is there another source for a mounting plate with the cutouts for the RTRM and the mini-breaker; that would also have room for the mini-busbars on each side of the RTMR?

 

If you cant find exactly what you want, power trays makes a full tray with the rtmr cutout. You could get that and cut off what you dont want.
