Hey friends. I need help, please, from someone with rear glass experience on years 1987½ to 1989 coupes (3.2 Carrera and 930 Turbo).
We're doing full bare metal repaint on a 1988, with all body parts off and using new rubber/seals on reassembly. When it came time to replace the rear window, we find that the black aluminum trim will not lay flat in the corner's radii.
Looking closer, I discovered that the original rear window trim (which had been there since the car was new) was
plastic, not aluminum. Investigating this with the help of my Porsche dealer (checking the VIN), we learned that there was a change in about mid-1987. Yup -- from that date until the end of the series in 1989, the rear window trim on coupe bodies changed to plastic (with its own part number) and there was a change in the shape of the barb that goes into the rubber seal as well:
- The black aluminum trim (PN# 911-545-911-00-70K and 911-545-912-00-70K) has a J-hook barb.
- The black plastic trim that I need (PN# 911-545-811-00-70K and 911-545-812-00-70K) has an arrow shaped barb (see the photo and pages from PET catalog below).
Oddly, the front trim does not change.
I cannot find this trim in stock anywhere — new or "new old stock." The parts houses tell me to use the aluminum trim (it supersedes the plastic part in their books) but my window guy has tried and tried to get the aluminum trim to lay down flat and it simply will not. Now I am in contact with Porsche's Classic Department in Germany to see what they suggest. If anything at all.
Any ideas? If so, it’d be greatly appreciated!
Thanks a million.
Bob
