On my '54 (sold a few years ago) I had it mounted behind the right front tire in the fender well. I also have it in the same place on my '46. Have never had an issue with it there, servicing it takes a little more work, but with a proper charging system that's once a year at most. I put over 100K on both trucks, still going on the '46. This picture is the mount on the '46.
