I am a fan of the vintage stuff and I really do like the Big Dynamic Drag slicks/Mag wheel combos. Gaudy sure but they worked well for me back in the '60s.
But I am confused... checking on eBay there are four different part numbers?
608, 609, 685, 686!
They all look the same as as best as I can determine all the same size.
608/609 (just a repackaging of 685/686)?
So if that's the case what's the different between the sets? 608-609 685-686?
