Small Bolt Pattern Wheels Don't Fit Wilwood Disc Conversion

So dude at PST told me I could get the wheels from classic industries. I called classic and they don't have anything that would work. I called wheel vintiques, they don't have nor can they build a wheel that will work. Wheel vintiques said even the 5 x 4.5 wheels they have, the 63 OE Chrysler that I have in 5x4, won't work because the center bore isn't the 3" that i'm being told I now need. Stockton Wheels has a SBP wheel, but the center bore isn't big enough. So at this point not only do my wheels not work, I can't find a place to even custom build a pair of wheels... Still going back and forth with PST about making this right. Really don't want to have to take apart the brakes but i'm not seeing many other options at this point, This is truly a bummer
