Easily fixed and easily broken I just put my sunroof back in and broke one in the process. Otherwise it was a success.

The part number is 911 564 127 00. It’s approximately NZD 11 from Design 911. I won’t order a replacement right now as my Spyder arrives in a few weeks and I may have other things to order. Name:  photo54.jpg

Spot on! Thanks guys, I'm building up a large order of small parts to go with my cv boots. Geez my sunroof seal is looking pretty poor as well!

Whilst talking Sunroofs, anyone know what stops the back end kicking up when closing, as I need to give mine a little push up to help it seal properly
Everything else works fine other than that...

It’s a purely mechanical action. The front runs up on the hinges, whereas the rear runs up on ramps in the rails. There is no adjustment. If you have to push it, maybe the drive is running out of strength to push it up, or one of the seals is interfering.

A note to others lucky enough to have sunroofs

The mechanism is very simple, but some of the parts are eye wateringly expensive.

The mechanism has no adjustment or limit stops. You push the button to close or open and a motor acts through two cables to pull or push the roof panel. When it reaches the mechanical limit it stalls the motor. The point of weakness, as I found, is the cable to carrier join. In future, I will be careful not to keep the switch on when I know the roof has closed. Otherwise I’m just putting unnecessary force on the join.

Thanks for the info, mine just seems to stop short of hitting home nice and flush...
I'll open and check the felt at the weekend to see if there is any obstructions?

Doh!
I let mine run to try and get it home...
Good to know.

Just having fun with mine. I noted mine wasn't quite square which stopped it coming up fully. Maybe that's your issue as well. I'll adjust it by undoing the transmission cover, manually pushing the roof fully closed then closing the cover again.

In my haste to fix the roof I missed a critical item. The right hand side plastic slider is broken on the part that guides the roof over the hinge. .

The new price is staggering for a bit of plastic. USD 29.

Final parts arrived for the sunroof. I installed a new slide (front had broken off the old one) and put a rubber washer on.

Getting ready for a road trip. Otto Fuchs come off and Cup 2 with semi slicks will go on. I’m also looking at tie rod wear to see if I can find out why my Spyder is so much sharper in its steering. Hard to tell if the inner tie rod is worn or not.

Let me know what you find out about the sharper steering. I’ve been chasing similar on my Targa and somewhat gave up with the thought that I could make a 30 yo car match a modern car. My current thought is that the steering rack could be the primary difference but I’m by no means an expert.

Considering the Spyder suspension is still very compliant I can’t imagine you need to eliminate all the bushings in the 964 suspension to get the same sharpness.

It's amazing how some parts have increased in price over a very short period of time. I buy most of my parts from Rosepassion and bought one of these for 3.66euro in Dec 2016, new price is 20euro!
Another part cost increase that amazed me was the plastic hand brake cover, bought for 17euro in Jan 2017 now 86euro!!

Yes, there are some shocks. You don't want to buy this type of part.
