Help! 15" Centerline needed

Seems like there's a set of those at every swap meet I go to you'll probably find one I'm sure
Ive been to several and SBP in a 15 is tough to find that is not Duster like with a huge dish and small backspacing. They are scarce, I ended up using an OLD pair from a Chevy II spec. Pretty shallow with a deep backspace for the lips they ran too. Wrong bolt pattern but a 5 on 4 pattern just fit between them and around the ring.
