1969 Camaro L.A. Trim tag symbol....

[BULLITT65]

So I was going through craigslist and came across this convertible, and when I looked at the trim tag pics, it appears the tag on this car has a (%) symbol, before the L.A. plant code sequence number. (it could also be c/o?)I am not real experienced with the L.A. format to begin with but this seemed like a odd symbol.
Is this common?

It is unusual; & 1/2 and - were also used at that time.

Thanks for the insight. Any significance to those other symbols vs. a letter ?

Doubt it.

For the most part, Van Nuys used an alpha-numeric code for production scheduling; A256 was the 256th unit scheduled for the A day of the month. Best guess, they ran out of letters and had to use symbols.

Van Nuys built several other models, not just Camaro.

I talked about this in a post a while back.
Somehow, they screwed up and burned through the letters that month.  Normally, they stop at Y.  They used Z and the symbols for the last week - only time that I've seen that happen.

From this enlargement (see below), it looks more like c/o

same meaning though, I am guessing.
