coolant overflow

You are unlikely to find somthing premade, unless you have more freetime than most of us to scour every possible source for a metal bracket. The simplest thing to do is enlist a sheetmetal shop to cut/bend you one out of sheet steel or aluminum. All you have to provide for them is a cardboard template for them to follow. The hardest thing about fabricating something like that is bending the sheetmetal in nice clean bends...you just have to find someone w/ a metal brake.

I made mine from metal (Aluminum, I think) that I got at lowes. My local lowes had pieces of metal about an inch wide, various thinknesses, and probably 3 feet long. It was pretty cheap, and it was located in the same aisle as the bolts, etc. If you can't find it, ask someone and they'll direct you to it if you explain to them what it looks like. I bent mine myself...probably could use a vise. But sure, you could have a metal shop do it if you want; it probably would look a little nicer if you had it done by a shop. No harm in trying yourself first though.
