My sunroof is getting cancelled!

In the 30 years I have owned my 911 I have opened the sunroof three times. In Acadia national park in Maine, In San Diego and Monterey, CA. Any other time the windows are up and the heat or AC is on.

My car is a fat pig at 2,741 pounds with full carpet and floor mats, and full OEM heater and four AC condensers and leather seats, a gallon of water in the washer bottle, huge battery. tool kit, and spare.

I recently did a glass out re-paint and had the sunroof deleted at that time. I opted for cutting out all the sunroof support sheet metal, retained the primary structural support of the roof and installation points for the bows (and additional bows now needed). Welded in the metal sunroof panel and the result was very minimal body work, filler, blocking, etc. and when looking at the roof, before and after paint, you can't tell there was ever a sunroof from the factory. All in, the incremental cost to do this on top of the paint job was ~$3k-4k. I had planned on repainting my car, so this was just a bit of added scope when I decided it was now or never! I'm not saying other methods/ways are wrong, merely offering my path as one solution.

Nice! So if you were to add the cost of paint and labor for painting the roof, that could be another $2500 (?) alone, or more) if you weren't painting the rest of the car, totaling $6500-$7500? So how much more or less than the $2000 I spent for the non-sunroof piece, plus the labor and paint to install and paint, maybe it's not that much more or if so maybe another $1-2k? I don't know because of all the other parts I'm having them prep and paint. Also I don't know if anyone else could do a complete gutter unfold and reinstall of a roof like they did, but I know they've already done it a few times, so that made the decision easier. Here's some of the Getty parts that they were working on and getting ready for primer before cutting off the roof. Fiberglass pieces that I thought looked pretty good as is, but Alex in this picture, pointed out all kinds of flaws in the finish, however minor, in the pieces and wouldn't let it out of his shop without reworking them. Nothing wrong with the fit though, those were spot on. I guess 'race ready parts' are beginning to end up as 'show car' pieces!

I love your choice of replacing the roof Steve! I don't think it has been noted on this thread but you will have also have the proper roofline for a sunroof delete car. A sunroof car has a slightly different profile vs a non sunroof car. A sunroof car has a slightly different bow to allow clearance for the sunroof to open and close.

I can't remember what my net loss was. I think I remember the inner structure, motor, and everything that went with to be on the upper side of that weight estimation you made. I did a fennlane weld in panel.

I wish you luck on your headliner install. :-)

Thanks for the wishes, but I'm not an upholstery guy, and don't have the time to do what seems like a multiday job that I'd probably make a mess of. Joel there tells me that one of his previous businesses was doing custom aircraft interiors, which is 100% more experience than I have so I'll just leave it to him. I did order the non-sunroof headliner rods from Jason at Stuttgart Classica USA, which I hear are the only ones know to fit right. Not sure OEM Porsche was ever corrected. Hopefully the install goes right and looks tight. I'll take some pics of it when it's installed.

I never knew that. I did hear that roofs in early 911s were shaped a bit different than the roofs in the later cars, but I never looked and noticed - maybe that's what you're talking about.

I'm curious about CBA's statement about profiles of sunroof vs non sunroof cars. I'll need to research this more as I'm very skeptical.

I do know that the sunroof panel itself is not the same bubble shape as the roofline, which is why some folks say not to use it as a delete panel.

That's why I used the old Fennlane panel, as it's English rolled to the right profile. The original panel is a different profile so that it can slide into the roof.

The roof replacement is definitely the best and that Is what I chose to do on my 77 for the sunroof delete. interestingly, it was a slick top from the factory and had a bad aftermarket sunroof installed a year after it was new.

Despite some saying not to use the sunroof panel to fill the hole, I've seen quite a few conversions done this way. The car I'm working on now did it this way and the roofline is imperceivable to a real slick top. I guess the question is how much filler was used.

Thanks to this 2020 thread...

911 Sunroof Cancelled

...and my lifelong hatred for sunroofs, I had Perfect Lines delete it from Vents, my 1989 M491 project car car, in 2021.

I was looking for A) increased headroom (my head hits G Body Sunroof ceilings on bumpy roads), B) strategic weight loss (I pulled 22.5 pounds of sunroof components out of the car) and C) improved aesthetics.



This picture illustrates the headroom opportunity cost associated with nasty sunroofs...



~1.6 inches from bottom of sunroof cassette to bottom of outer roof skin (i.e. the ceiling)...





The process...








The results...
















The full sunroof delete (parts, labor and primered roof section) cost $5,914 in 2021. I can only guess that it has gotten more costly during the intervening inflationary years.

Frank, it is thanks to posts by you and germanwheels that pushed me over the edge and down the slope to do this! So danke!

A bit of progress to report, roof has been welded on, and the internal shield for the rear roof vent - the piece that blocks water from entering the headliner/cabin from the rear vents, has been removed from the old roof and welded into the new one. Also I had Alex add some spot welds at the gutters to help bond the roof to the chassis to possibly improve chassis stiffening and strength, rather than just the crimping over it as the factory does at the gutters. Theres some body work and finishing has to be done to the roof, pillars, and gutters, prior to primer, but here below you can see the vent shield:

The 1975 911s that I have been posting about for a while is on the road. My last post was about it sputtering on the lower Rs. The general consensus was its been sitting for a long long time, put fresh gas and a injector cleaner through her and drive the sputter out of her.. The sputtering has gotten worse. So I took her out and warmed her up and sprayed the engine compartment around the area where the cap covers the 2 throttle bodies, and the engine responded .

So after looking around I found a vac line that was not attached to anything on one end. I don't know what the thing is called but it looks like the fuel filter but smaller some of the lines from it do go to the fuel filter and some go to where the injector lines come together . its the line that comes straight out of the top of that 'whatever it is"

I need to know where that line is supposed to hook up to see if it helps with the sputtering.

Update, the body parts have been primed. Here are some of them, to be prepped prior to paintwork. Everything is turning out very nice.




Note the cut outs on the underside of the rear bumper. This is to relieve some of the air pressure from the parachute effect of the rear bumper, such as you see done on all the later GT cars. Credit to Joey Seely's Project Nasty.



Those that know the RUF style bumper might notice that side curves of the oil cooler opening were reshaped to mimic more of the shape of an authentic RUF listed for auction at the most recent Air/Water event. Instead of a pair of half round circles they are now more a pair of tapered curves.





The roof has been welded on and finish body work completed, getting ready for primer:

Very cool to see this ready for primer.
