Sport Mirror Problem

[Green Machine]

Bought a pair of repro sport mirrors for our 70 C10. Did a trial fit/measure up before drilling any holes, driver side will be fine. Passenger side measures about 8 inches back from front of door to front hole of mirror, approx factory location, mocked up mirror as high as possible as backing plate will allow before hitting bodyline ridge above it, best location is about 1/2 inch farther back than factory location, as none of the top of the mirror is blocked by the vent window channel.

Even mounted as high as possible a little of the bottom inside corner is still blocked by the door, and a bigger problem is the the mirror cannot be tilted inward far enough to even catch a slight view of the bedside, the mirror nearly hits the base and runs out of swivel at that point. I like to see just the slightest hint of bedside in the mirror for an idea of where things are in relation to the truck.

I bought these mirrors from Chevy Duty and they seem to be good quality. Does anyone have any adjustment suggestions or should I try a different brand ? Or is that about as good a view as you (or anyone else) can get with the sport mirrors ???

Any good looking mirror options ??? Thanks in advance.
