Snaps

I'm working on a project at the moment and could really use some help with rim sizing. I will not be going the route that most go and installing "newer" Corvette rims. Some of the information I've gathered is lug pattern is 5x120.65 with a bore of 70.1 or 70.3. I need something around 17x8 to clear C5 calipers. My problem is I'm having trouble finding that bore. Any ideas?

Hub bore is 70.6 for my '87. Just went through the C5 brake upgrade myself.
