Well when I got the samurai there was no real support for the battery just some piece of what looked like it used to be the actual metal that rusted out, here's what I did:
1. took the grinder around the edges to even it up
2. measured
3. measured again
4. grabbed my old road sign from the basement
5. laid the lines out
6. cut what i needed
7. bent the edges
8. test fit
9. bent some more/trimmed a corner
10. installed the new tray

the finished product
