Let the...Moon...shine in, Part 2.

Springtime in the back yard at my house causes some interesting things to pop up on the lawn. With dandelions under control, sunroofs clips inevitably follow. Pictured to the right is a clip I've been debating on installing into the Nautilus. It's time to make a decision, so I decided to fully break it down to really see what I've got.

What a treasure trove of info in this little gem. With most of the headliner intact, I was able to carefully peel it off to retain for future use. My intents are to have a very accurate replacement made from the remnants of this one. To get the headliner completely loose, I had to remove all of the guide rail screws and remove the center front and corner rail pieces, as well as remove the coat hooks. I also had to break loose the side guide rails. Check out the picture below to see how the headliner was cut in around the corners. Under the headliner is a bead of rubber that protects the front edge and side edges of the headliner from the sharp body edges of the sunroof opening.

The sliding steel roof section also has a headliner frame that slides along in its own track, right along with the main panel. It is held to the underside of the sunroof panel by a combination of clamp strip and two corner screws. Remove the corner screws, slide the headliner frame to the front of the roof by 5 inches, pull it down slightly, then push it fully to the rear of the sunroof opening to completely reveal the underside of the sunroof panel. With everything out of the way, it starts looking a lot like the underside of a Volkswagen Bug sliding steel sunroof.

To remove the sliding steel sunroof panel fully, I decided to remove the sunroof mechanism transmission and motor pieces. This gave me the opportunity to compare these original 6 Volt parts to some Porsche pieces I recently acquired on ebay. Thankfully, Golde seems to have designed the operational sunroof assemblies for most of the European automobile manufacturers, which is greatly improves the sunroof enabled Type 34 owner's chance for finding spare parts! It also mades me wonder a little about Golde's ability to keep up with production back in the '60s, given that so may companies used their product. It might be that Golde licensed production of certain parts to other companies to keep up with the demand. Or, it might be that other companies had a better product. Either way, the original sunroof motor and transmission on this Type 34 sunroof clip were both made by Bosch. And, as it turns out, the 912 Porsche sunroof motor and transmission I bought through ebay are likewise Bosch--and 12 Volt! Which will make my own 12V conversion a bit more trivial, should I choose to do it. The mounting bracket attached to the Porsche sunroof motor is exactly the same as the one attached to the original 6V Bosch motor that came from this sunroof clip, too, which now makes me wonder about other parts such as the sunroof rails and cables. Check out those sunroof motor rubber mounts. They are part of an imprisoned assembly that appear to be tacked to the roof during assembly at the factory. Another interesting find was the body number for the sunroof assembly stampled into the transmission mount area.

Next time I post about Type 34 sunroofs, it will definitely include what I know about sunroof cables and parts interchangeability. In the meantime, it is interesting to note that this clip was from a late '65 through '66 model year car. I know this for a couple of reasons. The length of the sunroof motor to transmission drive shaft on this clip was the short one, which according to the parts books, started appearing on cars very late in '65. The second reason is a bit more obvious. The paint color is Bermuda, a '65 and '66 color, which someone at the factory conveniently penciled on the underside of the sliding steel roof section. I knew that the intended body color was grease penciled (usually red, black or white) into the right front headlight bucket, but this additional location came as a bit of a surprise.
