Suzuki DT90 lower mount

Anybody got any good ways of fixing motor mounts where the parts are NLA?

The stud that runs through the mount has snapped through corrosion. The rubber is fine so I though that I could remove both parts and replace it with some threaded bar.

Turns out that the stud is M12 as it goes through the mount and M10 where it passes through the bottom bracket of the steering tube.

Apart from buying second hand mounts from some ropey US website, anyone know where I can get a stepped M12/M10 stud?

Pic is of the mount after I'd ground the hex off the M12 end.

Ideas appreciated.

Not sure which thread has sheared 10mm or 12mm, whichever it is just ask your local engineering firm to drill it out on a lathe. Then re- thread the same size and screw a piece of threaded bar in - easy. Just make sure the engineering firm drill it out carefully so as not to tear the rubber bushing.

There's a hex nut where the diameter changes and it's sheared at that part.
Given the age of the motor (1998) I'm wondering whether to try and recreate the original part and ask them to turn down one end of a M12 rod and cut an M10 thread on it or whether I should open out the hole in the steering tube bracket and just run M12 all the way through.
