Change glass in original 240z side mirror?

[kurtwwalters]

I have an original 240z mirror - there is only a drivers' side - that I bumped into and dimpled seriously the 'dish' piece that the glass sits in (graceful @#&@!!). The glass is good - I found another original mirror with bad glass but all else is good. How does the glass come out? I have read a post on this, where he mentions a 'flag' and 'crimp' but I don't know what hls30.com means. It is a 2 year old thread, so I started a new one. Any help appreciated...

I have never been successful at removing the glass intact, but I have been more interested in saving the flag than the glass. The glass is cushoned from behind with a contoured rubber pad(pictured in that same thread), and the mirror is incerted, then the edge of the flag is bent over the glass-crimping it in place.

To replace the glass, you will need to break out the bad mirror glass, bend the edge of the flag open, cut the stainless to remove the glass on the dented flag, insert the good glass into the good flag, and re-crimp the edges.

I have tried this many times, and am making a buck and a die to handle the process for my ps door mirrors(9 hours to fit and assemble the convex glass in the flag by hand is way to labor intensive-even for a true OEM look) . I would de-crimp and epoxy the glass in the good flag-metal work bordering ground glass is an invitation for chips...
