BBP Rear drums for Abody 8.75

Hi, have an A Body 8.75 in my Dodge Demon.

I would like to go to Big Bolt Pattern and retain the original brakes. Is there a drum on the market I can use?

Even looking for a repro of the original and redrill the holes, just can't seem to find what I'm looking for. Somewhere like Summit is convenient.

Thanks in advance
