Rob, the hub extenders are machined pieces that resemble rings and are the
same OD as the centering flange on the GMC hub. They have a machined lip
that is the same diameter as the inner bore where the appearance cover
normally resides. I make them the same thickness as the spacer. They are
permanently attatched to the hub with flathead recessed allen head screws
drilled and tapped into the hub. There are pictures posted on the photo site
of my wheels, hubs, and spacers. just do a search under my name Jim Hupy. ...

There isn't a picture of the actual spacer. I assume the spacer is about 1/2 inch thick... Kind of like eBay Item number: 110626911565

Looking at your method, it looks like you could make centering flanges of almost any size.

This could open up more options for wheels and many Dodge or Ford wheels would work... if we had a larger hub center.

Yes, I know many lug centered wheels will work without any modifications to your coach... just lugnuts that match both the wheels and studs.

The hub extenders can be made to any width(thickness). I matched the width
with the wheel spacers that I also made. The purpose of the extender is to
exactly center the wheel on the hub. I tried to run the steel wheels and
spacers without extending the hub centers and it is a PITA to get the wheels
to run true. With the extenders, it is just like mounting the wheels on a
stock hub. The extenders do not carry any load, they only center the wheel.
The studs and nuts clamp the wheel, spacer, and hub together as an assembly.
I made a couple of extra sets when I made mine if anyone is interested in
how I did it.
