Default Flathead crank pulley questions

I have searched through all the pulley threads and maybe I gave up too soon.
So the issue is I have a 34 ford with a 1949 flathead running a crab style distributor and truck water pumps and it works great. I am building a new engine and I want use the same set up, but I can't find a crankshaft pulley that works. Obviously the guy that I bought the 34 from had a custom pulley made.
Who makes a custom crankshaft pulley? Or is there a Ford pulley that uses that will work? Thanks.

Truck water pumps with wide belts?

Is the stock 8BA stamped steel pulley too large in diameter to work with the crab cap distributor?

Yes it is. The diameter is 5 3/8 or so and I need about 5 inch max.

I have a crab on my '51 Merc engine. I dug up a photo from 10-15 yrs ago. I machined the OD of the pulley to clear. It wasn't a stamped pulley.

I can't say off hand. From what I remember it was just enough to clear the distributor. I can try to get a measurement tomorrow. I think there was a raised area on the pulley that I machined off.

This is the type of pulley I started with ( crazy price). The front pulley is approx. 5 3/8 inches dia. My machined pulley area is a little larger around 5 1/2". https://www.ebay.com/itm/1949-50-51-...wAAOxyxpxQ7475
