West coast mirrors

[notchbackgta]

Is there something about where the West Coast mirrors should be located? I am not sure if something like that would be in the assembly manual or not. If so I guess I should buy one, unless someone can post it for me.

I was going to buy the from Wess at Classic, but he stopped selling them, but said the Grote ones are similar. They are similar and seem to be very well made, but the mounting locations are not the same, it seems, as the holes that are already in my door. I am not sure if I should try to make the existing holes work, or weld those holes closed and mount them where I want them. I am just wondering if the holes in the door are factory or not.

This is what I bought
