The Valentine-1 mount only fits Valentine-1 Radar Detectors
You can determine the diameter of your stem by using calipers, using an open end box wrench that fits around your stem, (5/8,3/4, 23mm), a flexible tape measure or by very carefully using a non stretchable string/paper strip, wrapped around your stem and then measure the length of it.Then divide that number by 3.14 to get your diameter.
This is the Adjustable Valentine-1 Z Mount. It fits a 5/8, 3/4 inch or 23mm ROUND stem. You can move it up and down and back and forth. This works well with mirrors that have levers underneath them, balls, or are extra wide with buttons underneath them. It will work on all cars on the car list page and measures from 2.5 to 3 3/4 inches in length from the bottom of your mirror stem to the screw holes on the bottom.
Fully machine made from aero space quality 6061 T-6 aluminum and has been black anodized.
The Adjustable 3/4" or 23mm super valentine will fit on this type of mirror. The stem must come out the back of your mirror and be round.
This is the type of Round mirror stem that you will need for the Adjustable 5/8" Valentine-1 Z Mini Mount. This type of mirror is usually only used on BMW's and some Porsches and a handful of other cars. See car list. It is a VERY SMALL space and needs at least a 1/2 inch space between the mirror back and the windshield piece or you will not be able to move your mirror.
The Adjustable mount measures 2.5" to 3 3/4" and is 1/4" thick.

Idea For 5/8" Mount Only
Just received and installed the mount the other day. It's definitely a quality piece! The install, however did have its problems and I thought I'd let you know how I overcame them...

The car in question is a 1995 BMW M3 , but the mirror assembly in this car is basically the same for any E36 BMW (1992-1999 3-series).

Getting the 5/8" mount on the mirror stem was not a problem. However, when I went to adjust the mirror I had issues. Basically, because my legs are so short and I sit so close to the steering wheel , the mirror needs to be aimed to the extreme left. The space that the mount was taking up was preventing me from turning the mirror far enough for me to get a good viewing angle.

After a lot of deliberation and upon closer inspection, I noticed that the mirror housing had a lip where the stem attached to the mirror's pivoting cup. It appeared as though the problem could be solved by using a dremel to remove the "lip". Being of the adventurous kind (I own a race car so
I'm used to drilling holes and mangling factory sheet metal ) I took the mirror housing apart, then used a dremel to take the "lip" off. After reassembly, I was able to angle my rear view mirror perfectly!

The above modification may not be required for somebody who sits further back (and thus, not requiring such an extreme mirror angle), but I thought you might find this feedback helpful for any future E36 BMW owners.

Thanks!
