That new front end is certainly a big improvement. 
I think that I would have attempted to fix the stripped-out hole, if for no reason other than to see if it could be done - well, I'm sure that it could be done, so perhaps to see if I could do it.
The hole would need to be made progressively larger, then a plug inserted. I'd punch the plug from sheet brass of the same thickness as the wheel, then key it into the driver. The keyways could be done using a file for the hole in the wheel and a cut-off disc for the one in the plug (before inserting it, of course). The key could be a piece of brass bar stock. An alternative method might be to install the plug, then simply drill a small hole at the interface of the plug and wheel. A short length of music wire could then be pressed into place to serve as the key. The secured plug could then be drilled and tapped, and everything re-assembled.
However, since a replacement chassis is on the way, no need to even attempt it.
