I'm going to help add to your confusion.
I went through some old emails and found a bunch of pics i had to send to wedge when something didn't work out with the slider release bar. From what i remember, the sliders are reversible, meaning you can have the release bar on the inside or outside.
I think my seats required outside and they sent me inside. So i took some pics to show them.
They then sent me a new slider (for the record, it was one big experiment, so i was doing 1 seat at a time, i had yet to order a second). Well, they sent me a new slider set with the correct bar (which was drop shipped for them) and both companies refused to take the original sliders back. So i bought some round stock from home depot, bent and drilled a new bar and had 1 free set.
I found some old pics from the email to wedge, but i don't think you can go by the part numbers, based on the pull bar being wrong. But maybe it gives you an idea.
For the record, i'm a trainwreck when it comes to pictures. That's why i never post any around here. I have tons of cloud storage all over the place and 20 years worth of pics mixed anywhere and everywhere. These just happened to be in an archived email.
