It wasn't me that you spoke to, but i require some mirrors, and your tip might just fit the bill.
I've an old 95 model with small ID handlebars, what have you found?

Ok, here's a photo.
I wasn't sure how riding with bar end mirrors would be, so I wasn't keen to spend $160 to find out. But I have to tell you, visibility is about 100% better. The Mickey's only ever showed me my arm.
The stock S4 handlebars are threaded - an (approx 8mm dia.) bolt holds the bar ends in place. Well, these mirrors have an 8mm bolt which attaches to a collet which springs 'open' inside wider bars to hold the mirrors in place.... so I just removed the collet, and replaced the bar ends with the mirrors. The supplied bolts were about 1cm too long - so I bought replacement bolts for $1.15.
You'll notice I also wired the mirrors in place: it's not needed to hold them there - I'm just paranoid.
