Parts needed are
1"Chrome spacers (5/16 Inside diameter)and chrome lock washers available from
http://www.chromebolt.com 2 each plus 2 each 10mm X 1.25 pitch studs about 1" long( I cut mine off of a couple of grade 8.8 bolts and ground of the ends and chased them with a die).
All you have to do is get a 10mm X1.25 tap and thread the spacer all the way through, thread in the stud halfway into the spacer and put it back together with the chrome locknut between the spacer and the mirror so everythig adjusts normally. Don't tighten the mirror all the way get it close then spin the stock threaded collar up to tighten it and everything will adjust as before. The whole thing cost less than 10 bucks.
Here are a couple of picks if they work.
