I found them two diifferent places - A main had the rears and Ebay had the fronts. Mounted them last night to clean them up today. I will be giving a set to my friend to try outside next weekend.He also tried the others outdoors and they did not work.
When you find them there are two rings the outer will fit on the F1 rims with alittle sanding. Or you can follow the utube video on what you can do with it for a second set.
