Windshield replacement Front and Rear

[mickey356]

OK, I finally heard from the guy doing some much needed welding work on my 68 912…apparently I'll be getting it back this week sometime (next week probably). I had the rear windshield removed because part of the rear parcel shelf needed to be replaced.
Soooo, first order of business is a new headliner which means all glass out.
Did my research and it seems the front comes out pretty easy, pop outs don't look to difficult… I have all new seals for all glass already….my question is- Is it as simple as it looks to put them back in? This is what I gather -

Be VERY careful with the trim.
Use lots of soap or some other lubricant on seals.
Use rope to pull the inner seal through.
2 man job. Someone to apply pressure from the outside and someone to pull the rope through on the inside.

Do I use any kind of sealant to keep the new rubber seals better sealed? (thats a lot of "seals" in that sentence)

Lots of fun.
I did a front and rear on a targa.
Use soap and water not glycerine.
Put seal on window
Put rope in groove. I usee the round ends of 2 artist brushes to press in the rope.
Put in the trim.make sure there is only a1/4" inch or less gap between the sections and put the center connectors on.
Get the good aluminun glass suction cups at harbor freight to help lift/position the window
If you have a helper have them push on the window at the bottom center and begin pulling th rope over the lip of the car. Use the soap spray but not too much. Work your way around the window.
I put on the suction cups on the inside and fastened racheting tie downs to keep pressure on the window. Gentle
As you reach the lower corner take your time and see the seal go over the lip.
Slowly pull the rope to the midldle of the top of the window then start with the other end of the rope.
The corners are the trickiest.
Dont use too much soap.
Use a thin piece soft wood cut a radius into it. Slip it between the window and seal in the corners and tap on end of the wood to push the seal out and over the body to remove any gaps
Done took me 4 trys

If I remove front or back windows and the rubber is no good, I cut the rubber from both the in and putter sides, I leave the trim in place and cut around it, once its out, I cut the rubber around the trim. This gives me a unreformed trim to put on the new rubber.

When I reinstall the trim on new rubber after the window is in place, I press in the trim without any lube. I find it holds better this way for me. When I have used lube, I had issues with the corners popping out. I do lube the back side of the rubber so I can pull it through easier.

Make sure to use an OEM seal.

Everyone seems to have different opinions on what works best, this seems to work for me.

Best of Luck

Mickey... think you'll find mixed reviews on using sealant. Down side is if window & seal needs to come out and be reinstalled, sealant "should" be removed. A PITA. On other hand, 912/911 window frame design is such that frame tends to collect water at base of "A" pillars... leading to those areas rusting. Using a sealant can prevent leaks and rusting.

Good Idea to remove wipers when messing with windshield. If glass is not there and wiper snaps down... can damage dash.

Hire a seal to do the sealant and the seals in order to get a better seal. LoL!

I'm happy your day is finally here Mickey!

Thanks all!

The video Steven1070 posted is one of watched...making it look easy.
Another was that old Brit with the ivory 68 912 but he left a lot out and said it was a PITA. I think they used sealant in that install?
The rust thing is the precise reason I was asking...leaks lead to rust, and since I'm just now getting my car back from having major rust repair, I prefer to avoid as much as possible down the road
