Paul is correct, most MGTD’s came with a steel wheel and a “dog dish” hub cab.
I sold a 1/2 completed Ford based MGTD that had direct bolt wire wheels that were made by Cragar in the early 80’s. They were called Cragar Tru-Spokes.
Those wheels were painted cream colored and had a dark green pinstripe. THEY REQUIRED TUBES and would never stay balanced. In short…they sucked.
If I were you, I’d paint the steel VW wheels and use a flat Porsche style dog dish hub cap and get some stick on MG center logos for them.
If you look at Bill Collins’ car “Angelica” in the Photo Gallery, I built it using the rare VW “Baja Bug” 10 spoke steel wheels that I had powder coated.
If you find a set of real wires for the 4 lug VW pattern, they are going to cost well over $1,500 for a good set. However, you would have a better chance of finding Jimmy Hoffa.
