I have a friend who works in a metal shop.
Give him a drawing and measurements and he will make
the box or bracket you want. Alu or stainless steel is
what I have done with him. Let me know and I will get
you his contact info.

If you need something of an exact size to fit a particular spot, there's
a small business fabricating custom aluminium boxes about an hour north
of here, in Elyria, Ohio They do respectable work at surprisingly
reasonable prices. You can email or fax them a dimensioned drawing,
either rough or detailed; they'll make the box and ship it to you.
I commissioned them to make battery boxes for a scooter I was working on
last winter, and was pretty well satisfied with the result. IIRC, it
took them a couple of weeks. They stay pretty busy.

Even AWG 10 would be undersized unless you're stringing it overhead in
free air. Even then, loss from resistance could be significant unless
it's a very short run. Enclosed, #10 shouldn't carry more than 33 amps;
#12, not more than 23a. Normally #12 is protected (fused) at 20a and
#10 at 30a.
For 50a, I'd go with at least AWG 8, which IIRC can be protected at 50a
when insulation is rated 75 deg C and in conduit (I'm sure Roland W will
have the final word on this). AWG 6 would be better, safer, with lower
loss.
