I am looking for a mirror like this for the passenger side. Measures approx. 6&1/4" x 9&3/8". Anyone?

 

I would try looking at a parts store. If you can't find one to match exactly, buy 2 of the same.

 

I bought swans from MACs. After driving it, took the dinky little rounds off the swan arms and put oreilly's / advanced auto "generic replacement 6x9" on the swan arms - had to add a couple extra washers in front to use the acorns (and adjust correctly) - they don't look super great, but don't move around as much as I was cautioned they would. If I get rich or they move around a bunch on the highway, I think I will switch to jr west coast.

 

I think I will wait till I find at least a close replica as would like to keep the stock, farm truck look as much as possible.
