Replacing Convertible Top 1999 Cabriolet

[TNT79Bronco]

I purchased a VERY nice, 1999 996 Tiptronic Cabriolet , with about 139k miles, as a DD, for $8,000.  .Car is pretty much perfect, with the exception of the (you guessed it), REAR VINYL WINDOW.  The PO removed the window, because it was faded and cracking.  The rest of the top is not bad, but not great.  Shows signs of wear and slightly fading.  I thought about trying one of those zip in windows that you can got on EBAY, but I haven't heard or seen a post of ANYONE being successful at doing it.  The rest of the top is ok...not great.  Shows some signs of wear, but for a DD, it is perfectly acceptable.  However, I figured for a few hundred dollars more, I can buy a new top.  I am pretty handy with the tool kit and have no issues with taking out a transmission and engine, and doing work on them. and those types of projects.

 

Instead of plopping down a couple of grand for a new top and install at a shop, I thought I would tackle the replacement of the top myself.  Not that I have an issue with installers making the $1,000 or more to install the top, but I rather enjoy working on my Porsches and learning new things  Here are the questions, for those of you that have done such a thing, or have experience in such tasks.

 

HOW DIFFICULT IS IT TO DO?

How long did it take you?

Any TIPS or Tricks to successfully doing the job?

Any special tools required?

Any write-ups that you are aware of or videos?  (I did see the one for the Boxster, but that doesn't have the headliner and slightly different than 911)

 

If there aren't any write-ups for a 996.1, I might create one, with lots of pictures and explaination.

 

Thanks for any feedback or advice.

Glass sure woul be nice and preferred,  but i hear it needs to be manually folded in which i would not mind doing.
