Cabrio Roof Repair.

As some of you know I've struggled with my roof ever since buying the car last year. Wind noise, difficulty closing and then leaking (mostly my fault). I've embarked on replacing the front part of the roof and I've discovered that it isn't as easy as it looked.

I decided to ditch the headliner because it's filthy. (haters welcome)

I found missing and broken pieces and would seek your advice on the best way to handle it.
Case in point: I'm sure you recognize this assembly at the front roof line where it clamps to the windshield:

I hi-lighted the broken guide. (see below)

I found on ebay something they call a repair kit which consists of two guides (each side):

With shipping the repair kit costs ~$70, versus ~$285 for the full replacement latches.

Here's the question: has anyone used this solution? Buying the part is cheaper than buying the complete assembly but is it a matter of good money after poor results?

Here's the ebay link:

Metal strip in the middle and some sort of composite on the ends.
It might cost more but sometimes for certain part’s it’s good to stick with original or as close too especially going from a metal to plastic

Therein lies the dilemma. It doesn't appear to be a load bearing part but I have to wonder how it broke.
On a related issue (the next big problem), can anyone explain to me how the drive(?) cable attaches to these guides and how exactly the motor works at the other end. I've looked everywhere for an explanation and can only find glancing references to how it works.
There is a great description of the 450 cabrio top in evilution but I think the 451 is different.

I just found "den458" 's post from Jan 2022. using duckduckgo. Strange how I have better search results with a generic search engine than I have with this forum's search feature. :(
All ranting aside, this led to quite a bit of useful info. Thanks den458.

Brief update: I finally got the top replaced and working. Like most things I'll be faster and better next time.

Great but oh noooo, you didn’t snap no photos

I'll take some photos today in the sunlight. BTW - those Italian parts worked just fine. Time will tell if they last but for now it was better than buying the complete assembly The fact that those particular guides are being made separately tells me that this was the weak spot in the process. The parts I replaced were damaged or missing completely - it's a wonder the top even worked without them.

Finished up some details today and tested the open/close function.
1. I suck at snap connectors used in the interior panels. I break them, lose them, shoot them across the room and basically end up with a rattling panel.
2. The top wouldn't snap shut and I had to adjust the tensioning straps. This meant taking the spoiler off again (my least favorite job). These screws are smeared with waterproofing goop and I wonder if this is also on new cars or is it a fix-all done by a PO.
3. Notice the little bulge in the center of the spoiler. I think I missed the screw holes so it's not over until it's over.

Otherwise I'm pleased with the results.

I’m experimenting with the headliner. At first I thought it was trash but I found some fabric paint and “painted over” the sad stained grey h-liner. It looks good. Now a way to mount it since the rails are wrapped with fabric. Pictures to follow.

I'm really interested in your expererience with this repair. my 2008 cabrio has several broken spacers, etc and is currently sealed shut with gorilla tape.

I’d be glad to help and share the experience and knowledge. How deep do you want to go? I replaced the front section of the top, as you know, and learned a lot along the way. As I’ve said about many projects - I’d do better the next time.
Did you figure out the bulge in the spoiler or is it just slightly warped from sun exposure

Yup! I had misaligned one screw and it pushed the spoiler up rather than draw it down to the roof.

Well I'm 99.9% finished with the roof swap. You may recall I was going to scrap the headliner but decided to dye/paint is instead and go for a custom install.. The problem was I had wrapped the rails with the replacement top and left no room for the rubber strips that hold the headliner in place. You can see how I would wrap the rails with the cloth sewn into the seams where the rails go. (Cornell89's picture)

Well here's a very poor picture of my almost finished project headliner (ran out of snaps) The snaps are screwed in to the gap in the rails - through the wrapping - fit perfectly. I may get some black snap caps to hide the silver snaps.
