widening steel wheels

[ALLstrokedOUT]

Hello, ive been looking into mini-tubbing and widening the rear tires on my car to either 315's or 335's. I currently have a set of 17x9 steel cragar D-windows. Im wondering if anyone has a company theyd recommend for widening. Ive looked at Weldcrafts website, but they seem to specialize in high-dollar aluminum wheels..is there a company that can cut out my center section and weld it to a new drum that big? Seeing that i need steel wheels widened i would think they could be donw cheaper than aluminum could. I also saw in a Car Craft magazine that they had done this to their crown vic's steel wheels, but the company that did that is on the left coast, and im not.

Thanks!
