Eddie, The seal isn't a standard boot seal, as the lip is too thick. I found a supplier that does a similar seal, for a thicker lip. Should be able to forward the details if necessary, although he said at the time that he didn't have much left.
However, after further thought, I offer the following for consideration. 1) My car doesn't have a second seal between the lip and the bodywork, so the 'boot seal' is the only seal against water ingress. My old Porsche 924 had a second seal between the roof and the lip. I've been looking at how I could do something similar for the reasons below. The following assumes that my car is as it left the factory, and doesn't have anything missing. 2) At present any rain falling on the sunroof panel itself runs off the edge and into the channel around it. The drain holes are only 5mm or so, and in heavy rain the channel tends to fill. With a second seal the only water in the channel is that which has leaked past it. The rest goes over it and off the side of the roof. 3) Water tends to follow the lip round to the seal, rather than drip off it. This isn't so much of an issue with a boot or hatchback because of the angle of the panel. In most places, gravity stops this happening. As the sunroof is flat, the seal has to be perfect to stop it getting past. So it's very vulnerable to dirt or tears. This effect is much worse if the channel fills due to blocked drain holes or really heavy rain. 4) The metal section of the 'boot seal' means that it is difficult to join perfectly. On a boot or hatchback the join is generally at the bottom, where the water would have to go up the back of the panel to get past it, so it doesn't matter. On the sunroof, it's in the channel, so it does. An all-rubber seal that can be joined properly with superglue would not have that problem. 5) I would imagine that the second seal would reduce wind noise too, by getting rid of the panel gap. As an additional thought, you may need to put some type of flip-up deflector at the front, to avoid booming when the panel is removed. I haven't tried it with the Mk1, but it was unbearable in the Porsche if you pulled the deflector down at speed. My Mk1 has extra vents in the rear wings, done as an after- market modification by Quantum themselves. I wonder if they are connected to that issue? I've been looking at rubber extrusions to create a second seal for my car, but it's low on the priority list at the moment. If I sort anything out, I'll send you the details. I would recommend a look at one of the early Porsches, though. Once I had replaced the seals, it was a good design and caused no problems at all. Finally, my hinges have "L" shaped removeable pins, so that the roof is removeable. They look to have been made from 1/8" welding rods. Before it hits the road, they will be replaced with "P" shaped items - the thought of getting the end of one of them in my eye in an accident doesn't really appeal.....! The above isn't intended as any sort of criticism of anyone. I've never designed a car! I just hope it's food for thought in the early part of the design process. Dave.
