So I got a new set of volks but happens to be the valve stem are located on the inside of the rim and I want to get the 90 degree ones. I was looking up on some websites and I do not know what the measurements should be as in the height of the curve on the 90 degree and the length. I have Volk Gt-m. If you have any info please let me know.

One website I checked out

http://www.wheelcomponents.com/stems.html

I was looking at valve stem

512- which is 1.38 height and 1.125 in length
and
512a- which is 1.55 height and 1.125 in length

 

anyone know the correct measurements to get? Or any store that they purchased the right sizes?
