This morning I finished off gluing a couple of rogue edges of vinyl down on the knee roll that had lifted overnight and using my Swedish punch set I cut the small circles out where the side screws and cap fit, before leaving for work.
During lunch today I chased the new windscreen from Porsche Centre Portsmouth and picked up some more 3M 3/8” Butyl window tape from the Motor Factors as I’d used more than anticipated on fitting the rear window.
This evening when I got home from work I got the 2 stainless trims out of storage that go across the knee roll and sit at the bottom of the basket weave dash insert. The trim was held in place with a double sided tape which seemed to have a cloth inner (a bit like a material sticking plaster) The residue was scraped off and old glue removed with a little cellulose thinners before a good Brasso polish ready to go back on the knee roll when I can find some similar double sided tape.
Before Carfest I’d fitted the targa roof and noticed the window glass wasn’t level/parallel to the roof. The glass was up into the rubber end cap at the top of the quarterlight front runner, but with the roof now on, it was about ¼” (6mm) low at the rear leaving a clear gap into the car?
I’d looked at multiple images on-line of the glass to roof alignment, some hard to make out, but generally they seemed to vary wildly. I’d also looked at Kev’s daily driver and spoke to him about it at the weekend and had come to the conclusion that the panel and glass fit wasn’t that great originally, but certainly better than I had at the moment.
With the door panels off I thought I’d have a play around to see what could be done to make the car watertight
Before I’d fitted the roof, the glass was adjusted so it sat evenly on the vertical seals and the angles adjusted at the bolt adjusters on the base of the runners in the bottom of the door. I’d also adjusted the limit stop (B) so that the glass stopped when it reached the runner end cap at the top of the quarterlights, yet still the glass was low at the rear in comparison to the horizontal roof line. The glass needed to rotate ever so slightly in the door to raise the rear.
This had me flummoxed for a while because the short horizontal mechanism channel runner at the rear of the door held on with M6 hex bolts was as high as it could go, yet the glass was still low……….
After a bit of head scratching and trying different things, the penny dropped.
The mechanism is a sort of pincer, and if the distances between the two tops of the pincer are shorter/closer then the net result is the reach is higher. Since the rear part of the pincer is a roller in a runner (short horizontal mechanism channel in para above) and that was already adjusted as high as it could go, it couldn’t be that. However the front pincer top is a M8 bolt in a slotted block (A) which you can adjust.
Simply moving the M8 bolt to the rear (the block forward) allows the glass to lift further and change its angle/rotation within the door.
With the M8 bolt (A) slid to the rear, the end stop (B) needs to be adjusted again and another ¼” (6mm) can be gained at the rear of the glass before it hits the front quarterlight runner end cap.
RESULT…
Level glass on both sides that goes up to sit neatly on the Targa roof seals with no gaps for water or wind noise.
With everything adjusted I checked the windows wind up freely, doors open and close easy and then nipped up all the adjustment bolts to complete the job.
