I have a GM alternator setup for sale for a ’48 and older flathead. The bracket attaches to a stock generator mount, and has the correct wide belt pulley. I pulled this setup from a running car in favor of a Powergen alternator. The pieces need a good cleaning, but otherwise is in good condition. If you’re concerned about it being a 3-wire alternator, you can run a jumper from the sensing lead to the battery terminal on the alternator to essentially turn it into a 1-wire alternator. This setup new is around $170 – I’m asking $100 obo. I can ship these in a medium USPS flatrate box for $13 to anywhere in the US. Paypal is the easiest, but I can do a money order if not. Feel free to ask any questions.
