Quick Targa window install trick

[greglepore]

An upholstery hook is what looks like a curved dental pick (metal) w/ a screwdriver type handle. Snap on has them, among other sources. Perfect tool for reaching over the metal edge, hooking the lip of the seal, and pulling it over.

Hello Kevin
Thank you very much for the excellent explanation you gave.
I have just two questions more,like others i who want to know
what the ,,upholstry hook,, looks like.and what do mean with
,,defogger harnass,,and place it on the glass ?
In the week-end when my swollen fingers are recoverd i jump on the job.
Thanks again, from Oldtimer

Hi Kevin
I forgot something to ask,a friend of mine told me to insert
the chrome strip in the rubber before installing the window.
Because after installing no chance to get it in the rubber.
Is it true or is it possible to do it afterwards ?
Thanks and greetings from Hans

Thanks Kevin, it worked out great!

Two additions to your method.

I made a wooden construction to hold the strap since I didn't wanted to destroy my floor.

Since I didn't have a upholstery hook, I used the "double cord method". The first cord to seat the seal at the targa bar. The second to seat the bottom part.

The targa window is really strong. For the last (bottom) bit I asked my 11 year old son to sit on top of the window!

Cheers!

Ed

PS: Used an OEM seal. The most difficult bit was to get the seal around the window.

Ed and others who have done this. I see you have the gasket held in place with duct tape. Why the tape? Did you glue the gasket to the glass? Obviously you need to remove the tape at some point.

I have some black 3M weather strip adhesive I was thinking about using. I have done several rubber set windshields but never a targa glass. There doesn't seem to be any way this gasket is going to stay on the glass without adhesive.

I was even thinking super glue.

I did this last fall... the gasket will stay on once all of it is on the glass. The tension of the seal will keep it on the glass... I believe the tape was used as a starter to keep the seal on as it is walked on to the glass, more tape were put on further down the glass as more of the seal are attached. No adhesives or sealant were used... however dum dum was used on the frame.

The seal I have has two inner channels where it attaches to the glass. Does anyone know why? And which channel should I use when placing it around the glass? Inner or outer?

Weird gasket.

Wires on the inner, glass on outer.

Got! That's what I needed to understand. Thank you.

id appreciate some more direct advice about the trim in the older targa gaskets. ive read in other posts you have to put the trim in the gasket before instaling the window. however a glass installer i spoke with (who by the way tried for 2 hours to install my glass and quit) said the trim goes in after. from the pics on this thread it looks like you guys are putting the aluminum trim after.

is there a right way? does it matter?

thanks

Trim DEFINITELY goes into rubber before window goes into car. I did however mount the rubber to the glass before I fitted the trim and then I install glass, rubber and trim as a unit into body

[CountD]

TRIM goes in before the glass. No way you are getting the trim to go in after. Impossible. I tell everyone this and only half believe it - that is, until they leave the trim out for the duration of their ownership.

[redridge]

seal on the glass first, then the trim... then mount on the body.

[JohnJL]

Im doing this this weekend. I took the targa to a "restoration shop" and their "glass guy" a. insisted the trim goes in last, b. ruined my seal by ripping the lip while pulling the cord around then c. quit after 2 hours.

I've got a new OEM seal and am going t try that strap idea. I also got myself a big lever-action suction-cup to pull in the window from underneath.

Just to be sure I get the glass in the right groove, anyone mind confirming which seal pocket the glass goes in, A or B? This is a cross-section from the seal the glass guy ruined...

[rich]

I would say Glass "A"

"B" is for the wiring.

I have a glass installer doing the one I have here on Monday. He came to my shop to size up the job before committing to doing it. He mentioned suction cups from the inside and more than one guy doing it. I am here by myself so I gave up and called a glass shop. I'll let you know how it works out.

[redridge]

Glass is A.
B is for defrost...

see pic in post 31...

[JohnJL]

Thanks guys. Sorry to hijack the thread...

I got the seal on the glass, the trim doesn't just slip in there, do you guys use soapy water, or like the seal mounting on the glass does it work better dry so its grippy? I tried a little of wiggling the trim in dry but it wasn't easy so maybe soap and water helps?

Answered my own question and consolidating answers from other threads:

I am not sure how to remove the existing glass and seal, from memory I cut out the seal with a Stanley knife when I first bought the car. Also you may need to buy new chrome trim, it is difficult to remove and reuse without bending it too much.

So the Process:

- A Patient Assistant with strong thumbs....and a solid box to stand on, so they can apply more pressure when needed.

- Have a bowl and spray Bottle of diluted Washing-up liquid ready

- Place glass topside up on an old car tyre

- Fit a GENUINE Porsche seal to the glass

- Insert Clothes Line into groove. Start on bottom edge at 6 inches to left of centre. Leave about 12 inches hanging out (don't start ) and run around whole seal, overlap when you get back to the bottom, leaving another 12 inches free and put tape on this end.

- Fit Chrome trim. Wet finger with Washing-up liquid and rub along groove first. Take time to make sure it is properly fitted into the Groove, you will hear it 'Click' in. It will Pop out again slightly during fitting, but it is worth the effort to fit it correctly at this stage

- It should now look like this:




- Place some Washing-up liquid on the Lip around window frame of the Car.

- Place Glass with everything fitted onto Car. Spend time to make sure it is central, and make sure the hanging ends of the Clothes Line sit onto the Parcel Shelf.

- The Seal will sit proud of the body and nowhere near the frame Lip. Push on top of the seal, especially by the roof to get it somewhere near the Lip. Careful not to Pop out Chrome Trim



- Now the FUN abit !

- With your assistant pushing here, and you inside the car:


- Start pulling out the length of Clothes Line with tape on. Pull at 90 degrees to the Rubber, pulling directly towards yourself. GO SLOWLY...The idea is that the assistant follows you along the seal, applying pressure as you pull. Go really slowly around the corner. Continue 6 inches up the side, and then repeat the process with the other Clothes line Hanging end.

- This is what you are trying to achieve:



- Now it gets tricky. Go back to the other side and continue up to the top corner. The seal will sit Concave on the glass, but it needs to sit Convex against the body. Spray some Washing-up liquid against the seal and body. We managed to continue fitting the screen and then run a Childs Ikea Plastic Knife under the seal to pop it into the Concave position. HOWEVER I think it would be possible to do this process with the Knife whilst pushing down on the seal, just depends how strong your assistants thumbs are:







- I also made a Hook which helped 'Tweak' the seal into place from inside:


- Copy on the other side, and you should be DONE !
