Window adjustment, Can this gap be closed ? Options

[jim_hoyland]

There is a 3/8” gap between the front edge of the glass and the targa top rubber seal.
Car is a ‘75
Can the the glass be adjusted to close this gap ? How.

The roof and seals on the 914 (and proper alignment thereof ) are to say the least difficult. If you make one adjustment the other seems to move to requiring more twerking. I'm on the road now but if I had my maint manual I'd post up the factory adjustment points. there's not much as far as technique offered, but you can see the geometry changes.

One VERY large part is installation of the seals -
One of the biggest culprits is the seal on the roof that touches the top of the window.

The biggest problem I see with the seals is that most people try to pull the seals on the roof at the top of the window. Yes they can be pulled through the track, and you think that you have relieved all the tension, but in a month or more, the vibration / expansion and contraction will eventually allow the runner to return to the unstretched shape. Rubber has memory, and will do this, so even a small amount of stress will eventually cause this seal to mysteriously shrink.
The only way to avoid this is to install the outside edge 1st and them press in the inner edge. I making the seal about 1/4" longer than you think you will need. Install the roof and try to close the front latch. You will notice the seal will "beer can"or crumple in. Take a carpet knife and warm soapy water and shave off up to 1/8" and re try. Continue the process until you can see that seal is actually making contact and is under pressure, but not so much that it deforms the seal. This will allow for the best possible fit.

^ Good info. Makes me want to drive hundreds of miles and visit you just to buy your seal and have it installed right. (IMG:style_emoticons/default/smile.gif)

Since you're on the road, the factory adjustment points can be found here:

They helped me improve the situation. No longer leaks water, or much water, I should say—but the wind noise remains awful in a car that used to be really nice that way.
