I need to change 4 windows tilt as you can see in the photos. On the bottom window I have the number 7r while on the top window I have just the number 8 printed without neither letter "r" nor "l". I'd like to know which product I have to buy. I have to replace all 4 parts. Last question: do you have a store in New Jersey where I can come and pick up the products? Thanks
Francesco

This looks like an older version of the Series 140. A stamp of '8' on this coil balance system suggests you need the S140-8 8 lb spring system. The video below details how to remove and replace coil balance systems. 

I am afraid we don't have a storefront to visit, but we do ship worldwide and have a variety of shipping options for you to consider in checkout.
