I just had the same thing happen. luckily I had a spare mount.One thing I considered was getting an AN adapter that would allow me to drill and tap the mount to the next size and still give me the correct threads for the OE line.Summit sells quite an assortment and I'm sure they would ship to you, they probably have a depot in your country already.I may go ahead and do this anyway so I still have a spare.
I have one. How fast do you need it?IM me please
