I have a 74 and the trim tag reads 404 14L. I believe the car was silver with black leather interior. My book says 404 is black leather but what is 14L?
Here's my guess though I've never heard or seen it happen before.
The body build date is a letter follwed by 2 numbers so that can't be it.
In 1975, the paint code was 2 numbers follwed by the letter "L" which indicated laquer paint.
In 1974, the exterior paint code was 3 numbers only. Silver Mist Metallic was paint code 914. If you have a late year '74, it may be possible that they dropped the "9" in 914 and used 14L to designate Silver Mist Metallic in laquer?
Sounds crazy, but that's the only thing I can think of.
This site shows (14) and (914) as the same code, so my guess is that it is indeed Silver Mist Metallic in laquer.
The Corvette Black Book lists 14 as exterior color Silver Mist for MY 1974. It states, "Exterior color code on trim plates was generally a two number code followed by the letter L." It goes on to state that sometimes a 9 preceeded the two numbers with no letter following. Interior code 400 is black vinyl. Ref: page 69 in the 1953-2008 edition.

You're correct regarding the colour of the paint and the fact that GM went from 3 digits to 2 digits plus a letter in the late 74 time frame.
The L does NOT stand for lacquer, it stands for 'lower'. The GM system for identifying two tone cars was to use 'U' for the upper paint colour and 'L' for the lower. Monotone cars simply used the character 'L'.
Internet myth is that 'L' stood for lacquer and 'U' for urethane.

OK, so the internet myth started with a book myth. In any case the L does not stand for lacquer. Have a look at a Bowling Green trim tag, it shows xxL and xxU where xx is the two digit paint colour code.

...I did a survey on 1974 Corvettes the year they were the "Silver Salute"(25th Anniversary Celebration Car)and did some sixty cars there @ the 1999 Bloomington Gold Corvette Show. I had a car or two from the first day production to last day production cars. Have looked at probably 200-300 1974 Trim Tags in the last 15yrs or so and have NEVER, EVER have seen a "9XX" number for the paint code on any 1974 I looked at. Doesn't mean it didn't happen, I've just yet to see one.
...at the middle, right side of my "original" broadcast sheet for my Orange '74 Coupe under where all the options are listed it says...
80U UPPER ORANGE
80L LOWER ORANGE
