Just thought I'd add my 2 cents worth: Last April I bought my 48 business coupe. It hadn't been run for a few years so of course it needed all of the brakes replaced. I bought a universal puller from ebay. The guys address is
http://stores.ebay.com/MPP-TOOLS
The puller was only $48. It came in a nice plastic carrying case. It is probably made in China, but it still works fine.
My only complaint is that the threads on the post were full of paint, and the thread in the center piece was plated. I didn't have a tap and die to chase the threads, so I spent several hours, first with a wire brush, then cranking the post in and out to clear the threads. Once the threads were clear, it pulled the wheels in minutes.
