Yeah the OEM mirrors are pricey. I went with original round heads with short arm with the circle bases on mine. These are for 1961-63. I believe in 64 they went to the rectangle style heads with longer arms (still round base) and with 65-67 kept that style, but with square bases on the arms.
I'm not sure when the "West Coast" style of mirrors came about. I think these would be the best functional ones and I would have gone that route, but what I'm doing with my van... I need to have the ones I went with.
I think with the second generation Econolines they moved the mounting point back to below the vent window vertical post and still kept the rectangle style for a few years in addition to a couple of other variants. If you don't care about 1st gen originality, this position seems to have a big advantage especially with a rectangle mirror as it's out of the way of the vent window.
Anyway, I might not be correct in all I've said here, but that is what I've been able to figure out over the last couple years looking at pictures/brochures and catalogs. Also I have seen a lot of neat custom mirror set ups, but others will have to chime in on that as I never looked into those.
Here's a picture of a 1970 Police Van from a brochure with the rectangle mirror with long arm and square base mounted at the vertical vent window post.
