Cragar Mach 8 Spacers

I googled Cragar mach 8, and found an old Ford truck forum that gave some information about the spacers and a possible solution. Sounds like you probably need to get them made. At least the offset washers. Would it be possible to get the thick spacers machined thinner?
From what I read, the wheel is a vari-lug, and you bought what bolt pattern spacer you needed with it.
I'm sorry I'm not smart enough to post a link on here, but you could probably find it the way I did.
