How is it supposed to be secured? I am thinking bolt with washer, through valence and body of car/rear bumper, then washer and nut. What size bolt, metric 10 mm maybe. Should nuts, bolts and washers be stainless or anything to prevent rust?

I just installed one this afternoon. I basically did what you described and found some stainless steel screws. On the ends I used longer screws and some rubber washers similar to what was used originally.

so rubber washer to protect sheet metal and bumper, makes sense, sort of like the fender welt on a bug where the fenders connect

I have been looking for these fasteners for a few weeks. The ones for the ends are readily available at hardware store, metric self tappers are nowhere to be found, any suggestions on a source, dealer perhaps?

since it's only going into a speed nut, unless you're looking at a national-class concours competition, the US-sized hardware should be just fine.
interestingly, 4,8mm is a gnat's eyelash from 3/16" ... |

the picture is from ETKA - popularly known as "PET." available on CD through dealer sources now, for not much, and elsewhere. i'd go for a legit copy now that they're available... look around for "PET CD" and you'll find links... it has all the parts information for *all* the Porsche models. an invaluable resource even if you don't have to deal with a 356 Pre-A, a 914.6, and a '71 911 with '75 engine and '84 transaxle... as for the time - something of a sore subject. lots of stuff i need to be doing today, but you caught me finishing breakfast so it's an easy reply. my day job has me in front of a computer 8-10 hrs a day, so i can usually take a moment to help out. but there is much to do this weekend, many overdue projects i have to make progress on ... |
