Head marking #71 is a good one! As noted George and I both have it in our door hinges and I have noted that head marking on several other Camaro's but interesting enough I have only noticed it used for door hinges.

I'll change #71 to green "*" on my copy.

Just as a note; my 12A LA has all SEMS & RBW on the door hinges.

Thanks Chick!

If anyone has phillip head screws that you think or know are original to your car please post pics. And, since these small fasteners are difficult to photograph, please list any headmarks or grade-marks they have. Example; "E", "S", etc. The location of where these fasteners came from would also be helpful.

If you have trouble posting pics simply list what you have. This alone would be a big help! Trust me...I know what a PITA it is to post pics! ;)

Example below; I pulled these from the windshield squirters...how's that for a technical term  ???

Thanks!

Marty,

I bought a new camera which is slightly better than the old one, and I'm enclosing a photo of the original fastener from my car (WW tube hold down)..  PN 447143..  note that this is not a phillips screw, but instead is a hex fastener...

Nice improvement on pics Gary! Looks like the first pic is a plain hex GR-2 (no grade lines or headmark). What about the second one... maybe a GR-5? I can't quite make out the headmark.

And what kind of fastener do you have for the glove box striker? Is it a phillip's head like mine or is it also a hex screw?

The head marking appeared to be 2 concentric circles with some kind of 'delta' symbol inside it..?  but my vision these days is about as bad as my cameras.. :)

I will check on the glove compartment screws tonight and let you know...  I am thinking that is a phillips, but am unsure til I check...

Gary - Looks like you found a new headmark. Unfortunately there are only two call-outs for that one fastener and their both on UPC 1/A3 like you've mentioned. Please take a look at the other one in the opposite side of the vent grille and see if you can make out the headmark on it. Sure would like to add that one to the mix.

BTW...ditto on the old man vision syndrome.

Gary - I believe both you and Dave have the same exact fastener (PN 9421479); "A". Take a look at reply #76. His is from the same exact location and from another Norwood built survivor. The only other possibility would be #11 which is a bit of a stretch but I threw it in for comparison. Your thoughts?

Marty,

I examined some of the screws and fasteners this morning that you requested.
1)  The cowl vent screws (4 of them) are all identical (1/4" head, with 5/8" captive washer, w/ head marking the same as the prev photo showed - 2 concentric circles with 'delta' symbol inside.  Screw threads are 1/2" long.   Yes, it appears Dave's fasteners are the same as mine.
2)  The screws - also in the cowl vent panel - which retain the squirter hard lines, are also identical.  1/4 hex with a small shoulder, 1/4" long threads..   both are identical on my car and do not have any head marking).
3)  I removed one of the retainer screws from the glove compartment box.   It is 1/2" long, rounded head phillips , with an apparent dark phosphate coloring.  (photos attached).

You asked about 'other' Phillips screws, so I took a quick look while checking out the glovebox screws, and found these:
1)  End of dash pad - rounded head, dark phosphate phillips - no apparent washer, but I didn't remove the screw...  (see photo)

2) End of dash - rounded headed dark phosphate phillips with washer - I didn't remove it so don't know if it is captive washer or not ..(see photo)

3)  A-pillar trim - light colored flat head phillips (again, I didn't remove the screw).. see photo.

That A pillar don't look right. Are you sure that's A pillar and not the kick panel screw that's in the door jamb?

Gary - thanks for posting the phillip head screws. You have some real gems. Its interesting to see how they've changed over the years.

BTW- I managed to find two fasteners with the same 'delta' symbol. But, if you take a magnifying glass you can make out the "legs" of the "A"...your thoughts? The ones in the pic were taken from UPC 9/A5, PN 9429629.

Marty, I am not sure if I've seen this bolt shown so I thought I'd post it. Rear brake backing plate to diff. 3/8" x 24 - 1" dark phosphate. Note the nut is taller than normal, zinc plated, and used a lock washer.

Daniel,

Yes, that was a 'kick panel' fastener, NOT the A pillar ....  OOOPS!   :)

Marty:  Yes, it could be an A...   appears the same as yours, and yours is clearly an 'A'  ..  I couldn't see it that well on my fasteners.. but obviously the same head marking..
