Looking for true west coast mirrors and would like to see how they look on a 73-78 chevy
I think ANY mirror looks good on a 73-78 chevy

The west coasts are cool, but they give you a big blind spot right where you really want to be able to see good. We had an old dumptruck with those and I hated them only because they you had to get used to looking around them well before making any kind of left turn, or right for that matter. they gave excellent rear view qualities though, unmatched.
