TR2/3/3A TR3 Windscreen mountings

[oxendine]

I don't post very often but do read others daily. Can anyone tell me what length screw goes into the bottom hole of of the windshield stanchion? long or short? My frame was put together without the tenon plates. Is it possible to put these into place without losing the brackets when removing the existing screws? On more question. Is there any sort of gasket between the stanchions and the body? I can't seem to locate any from the big 3 suppliers.

Thanks, Donnie

The bottom hole gets a 1" screw, the two upper holes get 7/8". Be careful to get them right (and include the tenon plates) as otherwise it's easy to break the glass.

I'm not sure what brackets you are talking about, but my suggestion would be to remove the entire assembly from the car and lay it down flat. Then I believe you should be able remove the screws while supporting the stanchion in place, insert the tenon plate and put the screws back in. But it might be safer (if the screws aren't frozen) to remove the two small screws and plate (on each side) that hold the seal to the stanchions.

On the earlier cars, there was originally a kind of seal that fit into a slot in the stanchion. I've never seen them for sale, never worried about it much. Maybe someone else has a creative idea.

I think the later stanchions had nothing at all in there, but not sure about that.

Hi Don I am not sure what you mean exactly, but perhaps you feel your windscreen is too narrow to fit on the body because the tenon plates are not in the assembly and you need some wiggle room and that is why you mentioned loosing things up. My experience with the non-dzus windscreens is that they fit painfully tight to the body, so putting a gasket of sorts between the two is doubtful. If you have the room, then put something in by all means. The bolts/screws that fit the windshield to the body are 320-490 in the Moss catalogue. I would suggest putting the tenon plates or some substitute to get it stock and see how it fits.

Donnie, those 3 x metal threads per side joining the staunchion to the windscreen frame have been the source of many broken windsceens. If one hits the edge of the glass, it's goodnight nurse.

Originally, at least on the early cars, there was a thin strip of rubber between the tenon plate and the windscreen frame. It served as a waterproofer and a spacer for the staunchion metal threads. The factory windscreen drawings didn't show it and it's never been offered as a spare part.

The roll of glazing strip they supply (Moss 680-455) is fairly useless for the windscreen, as it won't sit neatly around the top radiused corners. However, at 1mm thickness, it's ideal between the tenon plate and windscreen frame. Any rubber up to about 2mm thickness will do though.

On post TS60000 cars the staunchions were bolted hard against the body. Not good for paintwork. As Steve said, they're usually a tight fit. I've used duct tape as a thin cushion, stuck to the back of the staunchion. It's a fiddly job, but helps.
