Trying to source rims for my brake swap...looking for a resource

[HeyRed]

Man...didnt think this would be quite such a PITA. I’m converting my 67 to power disk up front and need to swap out the rims to facilitate the rotor/caliper (my drum brake wheels wont leave enough room). I’m having a hard time sourcing some stock rims from 71 and up. Wheelsmith said they need the diameter hub-to-caliper of the kit (I don’t have the kit yet....waiting to hear back from POL) and Coker isn’t sure if their wheel would work.
I’m running 15x6 (6 lug) with the “nubs” on the outside of the inner ring for the 10” hubcaps that I’d like to keep. It would be easy if I went with steel smoothies, but man I like these stock hubcaps.
I’m gonna hit the junkyards Friday but thought I’d ask if anyone here has a good source for what I’m looking for besides Coker or Wheelsmith.

Or maybe someone has a pair they’re looking to part with.

Thanks.
