Thanks for the suggestions!
I like the Alan Grove bracket, and it's just inside my max price range (didn't want to pay more than fifty bucks).
When I converted my 8N Ford tractor to a 12V pos ground system a few years back, I spent a Saturday afternoon fabbing a bracket so it would tuck the alternator under the hood in the original location of the old 6-volt generator. When I finished, the bracket really looked nice, but about six months later I saw one for sale for $35. Considering the time involved, and with all the projects I have going as it is, I confess to often looking for the easy solution first, especially for something like brackets.
