No pictures, I bought a sheet of fiber type gasket material years ago, not paper type, that is around .030 thick.
I would use a stock type OEM oil pump to block gasket to trace that on the gasket material and trace the hole to the block bolt holes, cut it out and punch the bolt holes out with a hole punch and then install it with 4 3/8 short bolts with large fender flat washers and then cut out the oil pump snout hole carefully
