5.25 Inch Iron Flange

My iron flange measures 5.25 inches. The pipe drops down 3 inches and then the diameter narrows to 4 inches.

The flange is broken where the bolts secure the toilet and I need to replace. I bought a super ring flange replacement and that fits. However, the 4 inch wax ring I bought will not fit.

It there an expandable flange replacement that works for this diameter???

I checked the OATEY website and saw nothing. Is this perhaps a deep set flange???

What about a wax ring for this?

HELP!

It might be a deep set (4x4) flange. Will need a picture. If it is just a deep set flange, you can put a 3" long piece of 4" pipe inside it. That would support the wax.
