Most of the venders have them or you could try looking for a used one at the junk yard ,most look to be very similar. The one I have is like yours no night but I have compared it from a old toyota mirror and it is the same except for the attachment to the bracket.
Thanks for the info. I'm going to measure mine and try and find one that fits those dimension. Not much driving time left before old man winter hits so it's not something I'll need right away. Maybe the ole boy in Red will bring it.
