Its 34993B? I havent got one but it does state its size as M12 x 70mm and Mitsubishi part number as MB844918.
You could try Mitsu direct with the part number.
I have gone to a local Mitsubishi dealership and tried to order by part number, they are real pricks won't order parts for RHD "imports" here in Canada. I'll check with Mitsu Direct.
I have tried a M12x70mm from a local specialty bolt supply shop but didn't seem to thread in properly. I'll pick another one up from a different shop and give that a try though.
^ Im.guessing he means the window switch console for the drivers door trim??
Yes, this ^^
drivers window switch on mine is broken.
