I would check with some of the hotrod shops in your area. They will know where to get custom wheel work done.
If you have good fabracation skills, or know of a good custom fab shop, go to the HAMB web site. There are some post there in their tech section on changing wheel centers.
There are a couple of other wheel builders in California, look in some of the hotrod mags and you will see their adds.
I have heard nothing by sad stories about Stocton Wheels.
