This listing is for (6) window regulator arm rollers which is enough to do both sets of doors and is enough to replace all of the window crank regulator arm rollers.  This hardware kit does fit GM A body cars from 64-72 such as GTO, Chevelle, El Camino, 442, Cutlass, Skylark, GS and may also fit other GM passenger cars and trucks but be sure to match up your original hardware with the one in this listing.

The rivet measures .650" from end to end and the outside diameter of the rivet that the roller would ride on measures .295" at the large shoulder.  The part of the rivet that would enter the regulator or glass bracket measures .195" at the small shoulder.  The most outer part which is the washer part of the rivet measures .395" in diameter. 

This roller is a must for a proper restoration.  If you need a different style of roller or other hardware for your car please see my other listings or visit my store as I have more like this that are different sizes and styles.  You will get exactly what is pictured. Do not go off of the compatibility chart as it may not be correct. Please look at the photos and be sure that the roller you need looks like and measures like the ones listed.   The original roller is always very brittle, and often broken or lost when removed.  Now you can get your vehicle back to original showroom standards with this new roller.  I am a seller of the products I use.  This is the same roller that I use on my award winning concourse restorations here at Midwest Muscle Car Specialties so buy with confidence.
