Hey all... So I bought my first "aftermarket" set of rims for me SL4SH Ultimate and thought I had done the right thing, after watching the Ultimate RC youtube vid BUT, I have ordered the round wheel nuts instead of the 12mm hex and it doesn't look like they will fit the front hubs. (round vs hex)

Can someone please advise me of what I need to complete the task.

Mission: Fit RPM Revolver pn:82072 on to Slash 4x4 Ultimate.
Items already have: RPM 82072, Proline Trenchers, Slash (stock wheel area)

Items needed: Help coz I'm a NOOOB


oh and I cant send them back coz international ebay buy.... (Cheaper to buy replacement rims)
