I'm refurbishing my quarter glass windows on both sides. I have the new seals and the urethane sealer that you put on the surfaces. I cleaned up the stainless frames very well.

My question is, what is attached to the forward edges next to the door? There appears to be either or both a corner piece around the forward bottom corner or and piece that attaches along the entire forward edge. Either way something black either paint or a piece of rubber appears to have exist along this edge at one time. I have a set of 72 quarter glass as well, and there is some thick residue of some kind along those edges. It looks like old rubber. It doesn't seem logical that Nissan left this edge bare. My understanding is the the 280Z quarter windows had a rubber component riveted onto the forward edge. Black Dragon Automotive (bottom of page 13) shows a part #4 Seal-Front Quarter - LH & RH for 70-78 Z's. Anyone used this part?

So I'm a bit confused as to what was actually there. I'd appreciate some help.

Hey,...I just went through this.

The pre 1973 models only had a small rubber tab at the very top and another at very bottom of the window edge. These seem to be out of production now though. I agree that it doesn't look like Datsun would have left that edge bare,..but they did. Once it's installed and the door opening molding is installed it doesn't lok as bare.

The mid 1973 through 1978, (last 280z), had a full length seal. That is the one you referenced from Black Dragon. The full length seal is designed to attach by 4 screws that are in the window frame. Te earlier cars didn't have these 4 screws,..only 2 at the very top. Everyone will say they enterchange. However, you will have to glue the long strip on instead of screws as intended.

Now,..I replaced mine with the newer long version. It looks great and went on easily. However,..I have a very tight fit between the door frame and window now. It's almost too much. I'm hoping it will ease up after it's been on there a while.

Thanks. Well I know there was something black on the entire surface, it was not bright stainless.

If your frame has the 4 screws on the leading edge, (under your current black stuf,...then it came with the full length molding. If it is the 2 screw version, then it came with just the smal tabs.

I cleaned my up really well while I was polishing teh stainless.

No, I have a 71 model, it's original. There was a black finish of some kind on that forward edge.

Here is the "Upper Weather Strip" at the top of the side window. (Item 3 in the drawing above)

Item 6 in the drawing "Sealing Rubber" can be reused from the original.

It is difficult to see as it is squished and bonded. Here are two pics to help:

Pic of old seal in place... if you look closely you can see the "Sealing Rubber"

Here is is after liberation (it is two pieces of flat rubber):

See the dark finish along the edge? That's what I mean. Looks like it was painted. I'll probably reuse that built up part again instead of trying to fab it, because they appear to have tapered the rubber sections in the stack.

What's that rough residue along the forward edge in second photo?
