Hey Billy, this is what I came up with:
Get a piece of aluminum 37" wide by 9.5" long.
From the front, go back 2.5" and make a 90* up. 1 3/4" inch up, and a 90* back toward the engine.
Bolts from the left, are 4 1/8" to the right, 1 1/8" back. From the first one on the left, they are 9.5" apart going to the right. (Those are all measured to the center of the hole).
Once it is all bent, go 8 3/4" from the furthest back point on the top tray toward the center. Cut from that point back to the 90*.
On the right, go 5 1/4" left. Cut from that point back to the 90*.
Should look something like this:
I don't have access to a break.. Otherwise I'd build it now that I know how it needs to go together.
I'll pay you for your time / material / shipping if you want to try throwing one together!
There will be an issue with the positive power cable. From what I can tell, you'll be able to use the two center posts, but I don't think the outer 2 will work.. Will probably need to drill a hole and run a bolt through it and then through the cable tie. Should work.
