Sunroof Cable Nuts - Part Number?

[iamtheari]

I thought I had a broken sunroof cable because the roof didn't want to close all the way (rear remained dipped) and sometimes the right side of it would not move smoothly. I finally got around to taking the sunroof out an, lo and behold, the cables are fine - it's just missing some parts!

In the following picture, courtesy our host's technical article on the subject, the sunroof has been removed from the flat bracket that connects it to the slider, which is the part the cable moves. The bracket is bolted to the hinged part of the slider, and there is a special nut that locks the position of the bolt relative to the hinged part.

My car is missing this bolt and nut from the right side of the car. It's a mystery how that's possible, but alas...

What is the part number of the nut? (Also of the bolt, though of course that's a less specialized part.)

Thanks in advance!
