I recently put a Delco 10SI alternator on a '48 using the notes on the site. I made my own bracket though. It's a "stacked flat bar" with tabs style that I have seen on here a couple of times (and here I thought I was being original).
Hopefully here in a couple of weeks I'll have the hood on for good and can get that baby spinnin' !
And as far as part numbers. I guess I did get some from the how to articles. But I just went to my local auto parts house and told the guy I needed a 1 wire 10SI alternator. Told him a reman unit was fine as it wasn't going on a new tractor
. And just told him I needed a 12V coil with internal resistor. He had to call someone to get a number for that one, but he had it.
