Peep Mirrors

Does anyone know where I can get 4" clip style peep mirrors. I have a hardtop therefore no door frame. The clip needs to be about 1/2" wide to fit over the vent frame.

http://www.iandireproduction.com/ i got theirs . the clip is only 5/16" and barely fits on my door. 31 chevy. and the allen set screws they provide will be to long for me. they are 1/4"x20's and i think a finer thread would be better.
also tryhttp://www.fillingstation.com/
but call and ak whereever u buy about the clip .

I got mine from Speedway, not sure they are quite a 1/2" wide, I could measure mine if you want.

thanks guys...Bob I went to fillingstation.com and found a rain gutter mirror
looks like it will do the trick..for now..still going to serach for a clip on peep with a 1/2" throat

I found a few here: http://www.bigjims.net/mirrors.htm
