Hello there I'm new. I have a Honda hornet t reg. I bought replacement wing mirrors. If I take the original nut bolt out, and then put in the new screw bolt with the it fits perfectly. The old screw nut bolt is I'm told Imperial. The new screw nut is metric 10mm. They don't fit. I've been very where engineer shops the lot. Does any one know how to fix this please. The wing mirrors are to low. Many thanks. Zhak.
