Dear builder,
I would like to trade some MBS Rockstar II Hubs plus pulley if you also have some to trade 
for some Hypahubs to fit perfectly my mini spring truck 
…bearing 9.52mm can be arrange like wise if you also have some for me…but I think they are the same OD…
I also have some 8 inch road tires/inner chamber (like the kenda one) that could be part of the trade if you have some 6,5 inch or else on your hypahubs following with picture if someone propose some tires in the deal…;let me know if it OK since the tires will fit both hubs I was not especially willing to exchange them…
Cheers,
