ooooh, tricky one, its really rare for a second hand set to come up.
I sold half of my soul and an earlobe to get mine, well worth it - so if i was you i'd bite the bullet and sell a lung
Easiest thing to do is swap the hubs for ones from a 126, then you can get new wheels easier. Tyresave do a minilite style for the 126 called the Minotaur, but you do need 126 hubs Im afraid.
Thanks for info got a set ordered at reasonable price though had to get original minilights for 12" fitment. Any ides of length of bolts and thread needed for 126 hubs?
