Window Vertical Track help / Question

[Romoser.MD]

To my fellow ti enthusiasts, I come to you for help once again.

On our first warm spring afternoon, I got off of work early and decided it was time to fix the driver side window that broke late in the winter.

I was following the DIY regulator fix write up ( which is amazing by the way, kudos ) and noticed that I have a front vertical track...

but not a rear one?

This is not normal, and I must have bought the car without the rear vertical track and never known it.

I am looking on realoem.com for the part but I cannot find it. I also searched Window Track on ebay and various other things and could not find one. And I looked on Bavarian auto as well.

This may be because I am an idiot, or simply do not know where to look.

I am appealing to you guys for help finding this part (or part number) and if anyone is familiar with installing one or has a write-up somewhere?

TLDR;
1. Would someone please confirm that there is some sort of track that the window is supposed to be riding in as it is put down and starts to go down into the door? The aft part of my window is just free as it is lowered down in to the door. There is no track at all.
2. Do you know, or can you assist me in finding the part number for this track?
3. Do you have, or know of, a diy write up for the installation of the part?
4. Thank you.

again,
Thanks ahead of time!

I recently replaced mine. Here is the link to where I got mine. http://www.ecstuning.com/ES93756/

I think you are going to need the hardware too. It uses one 10mm bolt if I recall. I think this is it. http://www.ecstuning.com/Flyer-Forge...sport/ES15283/

As far as install goes, it's fairly straight forward. First, position the flared end over the upper rear window track. Then, remove the rubber access plug and install the 10mm bolt.

Aside from the track itself there is also the rubber guide that fits in the guide.

So the new Guide Rail came in today, along with the felt, and the bolt/washer.

There is already a bolt in the door where the guide rail should be attached.

I cannot for the life of me remove that bolt. I have a tiny socket wrench and a regular sized socket wrench and neither of them fit in behind to get a grip on the bolt. The head of the bolt is very hard to reach.

Does anyone have any tips on loosening this bolt who have removed the guide rails before?
