Bill, The thread about hubcaps was about fitting ”original” MG medalions to the VW hubcap. I think that British Coach Works was the only kit manufacturer to provide the larger ”BCW” emblem that covered the center part of the cap.
I still have not figured out how BCW adapted the VW wheels to their Chevette based cars. The VW wheels on my car had been replaced by the previous owner .I think he told me that it had 13” wire basket wheels on it when he aquired it from yet another PO.
The BCW Chevette cars used adaptor plats to fit the VW wheels, I believe.
No idea where one would find those now but other 15-inch steelies might work just as well. I seem to recall someone using Hyundai wheels on their ride. 15 round holes in them (as the TD had), and 15 x 5 rims. Could be mis-remembering that.
