Yep... got the exact same things in the same postion on the A...The mounting to the fender is fine...its the socket joint that seems never to be tight enough.. and like you said, your jumping in and out of the car three times to adjust the mrrors, or ( per usual) before the wife gets in the car.. its "Honey, can you adjust the mirrors.. up.. no down.. no left.. up again.. right...not so much!"
My first A I put a set of racing mirrors on, (the teardrops)... they look ridiculous way up front, but I placed them just far enough up the fender, to still see them out of the windshield..almost is line with the post, so they were in line aprox. with the vents grills on the MGA... they worked great!!
P,S. How do you post your picture,, I have not figured that out yet.. your B lookes Absolutely great!!!!!
