1969 rear license plate bracket GM 3913608

[Danzo]

Does anyone have a picture (front and rear) of an original? Was there more than 1 supplier?
Thanks, Doc.

Top is OE '69. Bottom is GMPD substitute up to the '90s.

Try these. I apologize for the scroungy appearance - off my X77, disassembled in 1980 or so. Front, back and part number stamp. The original bolts are on the bracket, marked with a single "P".

Regards,
Steve

William and Steve, thank you!

I think at least 2 suppliers is likely, many have AAc stamped on them but I have also seen them stamped with a triangle symbol containing a letter (including the one on my LA car).

Were they basically 60% or Full gloss, dip painted, runs and all as an assembly,,,,,

There is different font sizes that you have to be aware of.

Mine is exactly like Steve's (z28 z11). Norwood built 8/28/1969....Joe

I looked at the other 2 - the 03D Pace Car is like the 01C X77 - stamped GM and part number. The 12A '68 built L78 is different - lot of surface rust, appears either to be an AAc or triangle marking, I'll have to give it a bath in Evaporust or the old electrolysis routine to be sure, but it is different. All were built in Norwood, might be a vendor change somewhere in the first part of the year at Norwood. Need more examples to find a pattern -

The production line fonts were a little different than the ones produced OTC

I'd say you're right at 60% gloss - definitely more gloss than many of the supplier parts. Here are photos of my original bracket (partially stripped for paint) from my 2B Norwood RS/Z:

Great to see another 'P' in a triangle, Lloyd - and clearly not just an LA plant supplier then!

Tim and Lloyd,

Triangle/P on the same bracket with the GM part number stamp as well ? What area does it appear in ?

Steve

[x66 714]

Steve. They're on opposite sides from each other....Joe

[z28z11]

Man, I gotta clean these up a bit. I thought I looked them over pretty carefully, but old eyes can fool you. Sorry I missed the obvious !

Thanks,
Steve

I know about old eyes. I have to get my readers out all the time

Yes, mine has both GM part number and 'P' stamp, and as Joe said, on opposite sides of the bracket (also just like Lloyd's). You can make out the 'P' stamp in Lloyd's first picture, bottom right corner, around the 3-3/8" mark on the ruler on top.

Same here. I resisted as long as I could, cringe every time I have to step up the magnification on my El Cheapo OTC readers. I'm gonna wear them in a minute to look for the triangles on the two in the garage -

Lloyd - thanks, I know where to concentrate my excavating. What process are you using to prepare this - vapor blast ? Really superior -

Steve, what you see in the photo is the result of dry media blasting only using fine glass bead at 80PSI. The fine bead produces a near-polished surface which sets up well for paint. Following media blasting I'll sand the piece with 400 grit paper to "knock down" the surface then mask off the GM part number and manufacturers stamp before a thorough wipe down with prep sol followed by a light coat of epoxy primer.

Here's the finished product. I had previously restored an NOS bracket for my project only to discover the part number had been superseded (so that won't do) and the finish I applied was 30% gloss and I now believe it should be in the 60-80% range (or full gloss by 1969 standards).
