Got a quote back from Superior Tire & Rubber Corp.
Email went as follows:
***************
"Knowing that your machine will be in a wood, marshy environment, the only track pad that is going to withstand this is the polyurethane mold on pads. We can do this one of two ways – if you can afford the down time on your machine (say this winter) you can send me your steel shoes and we can mold the poly directly to your steel shoes. OR, we can buy new steel shoes and mold polyurethane to them.
Here are what the costs would be:
24” Poly Mold on to your steel shoes: $128.00
24” Poly Mold on to new steel shoes: $205.00
Lead time would be 4-5 weeks lead time after we received the steel shoes.
I know this may seem like a lot of money – but trust me the other options of pads just will not withstand working in the woods. I look forward to speaking with you about any other questions you may have."

Quick count gave me 84 shoes on the excavator. That times 128 is just shy of 11k$. Not a trivial purchase.
