Replacement for a Ronthor backplate patent #5857233

A quick learner says:
Is the 32-031 the correct replacement for a Ronthor backplate patent #5857233? I have found similer types, but none that fit. Thank you, Dick

Yes, Ronthor patent number 2857233 is referenced for this product. Still check what dimensions we do have online for this product in case this patent was used on more than one size.
