Sorry to hear that. If its covered on your insurance then the windscreen repairer will usually be able to source one. I had one replaced on a classic policy.

Couple of questions:-

1) Are you using a Vixen Screen Rubber as opposed to the M one as it has a long flatter lip round the outside

2) When you go for Vmax are all the windows and roof closed? If so, then I suggest opening one of them a little on the next run

Looks like its on the insurance so that takes the edge of it

1)Windscreen rubber bought new from DG's I think during the rebuild but to be fair I asked for an M part rather than a Vixen item and that's what they supplied. Why wouldn't I? Live and learn.

2) Yes the windows were closed but I have also witnessed a back screen eject from an M with the windows open at silly speeds and I would rather buy a front screen if it had to be one or the other. (Fuzzy logic)

Been f**king about all night in the garage as you do and put the screen back in properly. The break is so good you cant even see it now its in, so should be OK for pottering about in for a tad longer to get these shocks right.

Have now mentally decided upon the steel rod remedy for future.

Good to hear you got a screen sourced and fitted easily enough DY. That was a pleasant surprise as I thought it may have been a bit more involved and expensive. Cheers, I shall go to bed slightly happier.

You need to speak to Adrian Venn and Order the correct rubber from him and follow his correct method of installing the screen. Adrian Bonds them in place to prevent the occurance.
The steel support rod won't harm anything though.

Thanks for that Neil...the common cause for the screen trying to part company with the car is normally using the wrong screen seal, I cannot say what you have in your car is right or wrong without looking at it BUT several things are constants when purchasing or spec'ing the seal. The shore rating is what gives any seal the flexibilty to turn the radius at the top 2 corners, all seals come with a minumun radius rating, then the measurement of what can go into each side of the rubber 4mm glass/metal, 6mm glass/metal and 4mm glass/4mm glass etc. IF you use the wrong rubber seal then the glass and in this case fibreglass does not fit up to the centre support and just gets pinched and forced out to the edge of the screen seal and the locking chrome cannot do it's job, no matter how much sealer is used. Across the internal body shell of the M should be a rope/bonded streghtener I have known these to be missing and this allow more flex in the shell, sunshine roofs do not help as they allow flex too. Mine is the ealier seal as fitted 60-75 which has the secondary lip on.

I was quite amazed to discover that my 2500M did this thing with the windscreen when I first bought it 16 years ago. A lot of TVR folks knew about it. They recommended that I just open a window a bit and everything should go back into place. Sure enough, that worked.

With the car all sealed up, at high speeds, you can see the glass and the seal begin to part at the top. This is revealed by being able to see the seal mark witness marks on the glass. Open a window, even just a bit, and everything settles down.

I've never had such catastrophic issues, though, even when at speed with the car buttoned up. My windscreen and seal are both original.
