I would like to confirm that the S770-28 with the 28E strength is the correct window balancer to order. The primary difference between the old balancer (see pictures) and your S770-28 is the old balancer attaches with an S-clip versus a screw. I would also like to know whether you recommend also replacing the pivot shoes. The original parts were installed in 2006. I am assuming you accept al major credit cards for payment.
Thank you!
Bob
