Replacement skids for 54" blade?

My neighbor stopped by yesterday to ask me if the chunk of metal he found in his driveway was from my tractor. Left skid from my 54" blade wore through and broke off in the past 4-5 days when I was plowing our common private drive as well as his driveway. The right skid is almost the same (I plow a lot with the blade angled to the right, so I guess it makes sense that the left wore out a little faster).

Now for my question. Before I go the JD dealer and buy replacement skids, are there any better alternatives out there?
