The wheels on the white one are bart stock car wheels they were around ?50 each I think, I cant remember where I got them but the company was a pain to deal with anyway, to be honest the quality isn't that good, I had to get them repainted after a few years, did it in aircraft paint at work so it should last a bit better this time, maybe the american racing ones are better
The '72 is an original U code 440 rallye(but not the original colour etc..) been off the road for a while for loads of minor jobs, I'll try and dig it out one month
