I remounted the knock off on one rear side (yes, I know it is on the wrong side- just temp mock up). It turns out the due to the snug fit of the pin drives- it does only add 1/2" to the hub.
But that still left the wheel sticking out 1 1/2". So I purchased some 2" fiberglass flairs. I temp mounted one onto the rear fender just to see how it would look. They are normally a screw-on for race cars and come in black fiberglass.

If I keep the wider rear wheels I need to increase the fender width. I could glue them on, and add glass filler to blend them into the fender. Trying to decide if it will look OK.
It will cover the wheel at the top.
There is a lot of space above the tire and wheel arch on the rear as the car sits now.
As you can see from this finished CR on a side view, the rear arch is very high, So I think the added flare will actually improve the sizing.
Do like having the 9.5" rear wheel vs the 7.5" that would fit under the stock fender. I will just have to work with the fiberglass to make sure the added flare looks not like an add-on.
