I like the logic there... and of course, it makes perfect sence.

But... Mirrors change in their adjustment.. especially when attached to doors that get slammed, bumped into by pedestrians (hopefully when the car is parked), trees jump out.. you know.

So, always being able to see the rear corner of the car in the mirror allows me to know it hasn't changed adjustment. For the rest of the blind spot, I've really grown to like the little stick-on convex mirrors that sticks to what's already there.. takes a little getting used to.. since vehicles in there look like they are a mile away, when they are actually even with your rear axle...

But as you say.. you get used to it.

As for the problem at hand that started this thread... I can't say. Any time I've installed a mirror, I size it up first to see if it will work ok... rather than just measuring and drilling. have you compared your new mirror to an original to confirm that it's arm is the same length, same angle.. etc? Mirror itself same size?

Can you rotate the mirror itself 180°? Would that make a difference?
