Hi!
I got the Ford wheel at my local dealer (£20), but it is not a straight forward fit.
It has a 32 mm hole in the middel and that is no way near the 1/2 inch bolt. I then bought Omex wheel from Burton, this one has 20 mm hole.
I have not decided which one to use, but either way, I will have to get someone to make an adaptor to center the wheel. I will then bolt the wheel to the crank pulley.
