Please ignore my previous attempt at an email, I did not include all the necessary info.
I have purchased the wrong balancers in the past and the windows begin to open correctly and without resistance. But then they get stuck and won't open any further. The issue is the width of the "ears" at the bottom of the balancer. I end up grinding off some of the plastic piece that sticks out from the metal channel. Please see the pic "EarMeasurement.jpg" for a better reference.
The balancers are .5" wide and I have two different lengths needed. The metal channels are 29" and 17". Part number ordered prevoiusly are 16204 and 16404 for the 17" balancer and 2830 for the 29" balancer. I'll need two pairs for each length.
I'm also looking for balance caps, do you have metal ones?
I really appreciate your help in identifying the correct parts,
Shauna
