Our patented Rectangular Clear Shot Mirrors for 1968-72 GM cars eliminate the passenger side blind spot by allowing the mirror to be adjusted further in. There are two countersunk screws in the back of each mirror head that adjust the tension of the stainless steel ball and socket, which screw into the mirror base. This makes sure the mirror stays where you adjust it instead of falling down while driving. Each mirror mounts to the car like factory with hardware that is included with each set.
** Please note that our mirrors are made to look as factory as possible, but will not match factory mirrors exactly.
