The 5 lug motor wheels are a bit hard to find. Chevrolet never used a 5 lug pattern and GMC only used them until the early 50's. Im taking a trip to California later this year to pick up a set since I cant find the wheels I want any closer. I know where a good 50+ Budd wheels are within about 5 minutes of my places, but they wont work even though they are on the same concentric circle and are sized to fit my hubs.
Any shop that does tires should be able to set you up. A friend of mine manages a Les Schwab and it took him about 5 minutes to come up with what I needed.
Another option would be to change out your hubs for an easier to find bolt pattern. I recently rebuilt my rearend and upgraded to 5.43 rear gears. Being stubborn (I like the 5 lug look), I used a 1953 axle with Bendix brakes and I wanted to keep my 5 lug hubs, so I picked up a set of 6 lug drums and had the lug holes welded, and a retired machinist friend of mine redrilled for the 5 lug pattern.
It came out REALLY nice!
