HELP NEEDED….

Hi,
I have nearly completed my restoration of the factory Budd brakes on my 68 Chrysler New Yorker, I have fitted a nice pair of used rotors, rebuilt my bottom ball joints so it is nearly done.
I ordered a pair of reconditioned Budd calipers from Summit Racing, i received the Left side caliper and very happy with the product.
Only big issue i have is that the Right side is on back order with Summit and has been for 2 months now, they are now saying they can't locate a right side...

HELP NEEDED....
