Hey there, thanks for the nice video I found online. Looks like I need 79-128 but I would love for you to peek at must pictures to make sure. Also when looking at picture of our storefront. I am replacing pivots for the door on the left. Not sure if I need left hand or right hand since depends if im looking at the door inside or outside. Thanks

It's tough to tell exactly which type pivot you need for your door, but it does look like you need the Right hand side. Make sure the 79-128 is the type pivot you need. Take a good look at the mounting holes in your pivots, that's usually a good way to confirm a match.
