41U = PRIMARY COLOR EXTERIOR, BLACK
51A = STRIPE COLOR ACCENT, TWO TONE, GRAY/SILVER
96U = PRIMARY COLOR EXTERIOR, ULTRA SILVER MET
WA L9150 = Black
WA U8807 = Silver Metallic
ASTRP = Can't find this one but probably the stripe like df2x4 said.
82D = TRIM COMBINATION CLOTH, MED DK GRAY

According to GM RPO Master List, except paint codes.

The U and L isn't apart of the paint code itself, the paint codes are WA9150 and WA8807, so U and L is Upper and Lower. I think your truck was upper half in silver and lower half in black with the grey/silver stripe between.

Are you sure that's correct? Specifically the two "Primary Color" codes, shouldn't there be one primary and one secondary? If you really want to know for sure, you can run a CompNine VIN lookup. That's what I did. It used to be free, now it's either $10/month for up to 1000 lookups, or 5 individual lookups for $5, no subscription necessary on that last one.

You should have 1 color ##U (Main upper color), one color ##L (secondary color), and 1 color ##A (accent/stripe).

96U is the same as my truck, it was a primary "ultra silver". I have no idea where MsChevy got two ##U numbers because that doesn't make sense. Just for the record 79A is a "dark carmine accent". I don't believe your vehicle was two tone judging by your RPO codes.

EDIT* What color is your truck now?

Silver truck, no secondary color, dark carmine (red) pinstripe/accent.

Check the engine bay? Someone went through a lot of trouble to paint it black. Check the rear fender, if it had a second color you would see it there.

Where is that code WA L9150 because it isn't an RPO code.......

Is it on the gas Door or the inside door jam? Possible replacements.....
