David:
The base you have is not a standard size (as offered by Boxcar Press, anyway, as theirs are .875” and.853” to fit their standard size plates. if yours plus the plate on top is really 29/32”, it would be too high for any relief plate. Perhaps the top surface could be removed, leaving the height at 13/16” (.8125”). It could then be underlaid to bring the base plus plate up to the proper height (.918”).
