I followed the recomendation in this group and got the Midwest gear too.
Shipped to my door, it came to $23. This is heavy duty stuff.
The package included a set of axles, which was a nice surprise.

This gear is noticeably taller, and a shade narrower than the stock Lanier gear.
I don't think this will harm anything. I can always bend it if it doesn't handle well.
Apart from that, as Redrata said, fits perfectly.
