Looking for PN for the 8mm bolt used to attach item 10 (lower rear quarter) on sheet 810-35 to rear fender. For 1987 911. PET doesnt show it, as confirmed with PP tech support.

Is sheet 810-35 a page in the factory repair manual? How about posting a picture and we can better identify it.

Sheet 810-35 is actually illustration 801-35 on pdf file page208/506.

OP just needs a simple metric fastener. I cannot find the PN either.

Aha I know what he's looking for. It's the small coarse thread screw with an 8mm hex head on it. These thread into the blind clip-on nuts on the body flange. Porsche calls these nuts "speed nuts"

I agree the part number is not listed on that diagram. But that same screw is used on the front bumper assembly too. Its part number 900.187.018.02, described as a "tap screw, hex head, size B 4.8 x 16" Its part number 16 in illustration 802-01

You can substitute an English thread screw for these, since the threads are coarse and you're threading into a blind nut. I use aluminum screws with a 3/16 head on them. I get them at Ace Hardware. I think the screw is a #10 in the goofy screw numbering system used in USA Machine Screw Size Charts and Conversion Tables

Apologies for this off-topic blurb, but I enjoyed perusing through the PDF file that Bob K. attached. The exploded view diagrams and part# callouts and nomenclature are very useful... which prompts the question: Are there too many substantial differences between an '85 and an '89 Carrera to make this unusable for my '85?

No worries about 85 vs. 89. Porsche put together that pdf to cover the 3.2 car series. They do a good job of updating their parts and parts reference material so that the superseded parts are almost always reverse compliant or back-datable.

The biggest difference in the 85 vs. 89 is the transmission. Otherwise the car is basically the same aside from some more subtle differences like headlights, switchgear, some HVAC stuff.
