I have for sale Lange Originals Quick Mirror I. Never been on the vehicle, but been modified to fit more secure in the hinges.
Quick-Release Mirrors fulfill side-view mirror requirement laws and install instantly. Quick Mirror I fits into the upper door hinge socket. Modifications made to the mirror handles: drilled in to the mounting point and threaded to accept a thin bolt. You can see in the pictures bolts coming out of the Lange supporting braket.
You can still use it as it was designed by Lange or use my mod to make it more secure.
I am asking $50 for both mirrors plus shipping.
