Edit: I was sorta off actually...fixed info...
Not sure if we're talking about the same thing for sure, but I found the paint codes for the body and trim pieces I was looking for... My LX470 is Blue with Gray molding/trim and using t o y o d i y . c o m , I decoded my VIN to see "COLOR CODE: 8P6" and "TRIM CODE: LG10".
The piece I was looking for is 75850A in the image (highlighted in yellow, but for the RH side) my choices for my truck when I entered my VIN were:
75850A MOULDING ASSY, BODY ROCKER PANEL, RH
75850-60010-A2 WHITE PEARL CS., 070
75850-60010-B0 GRAY ME., 6T2 , 8P6
75850-60010-D0 DK. GRAY M., 1E9 , 202
75850-60010-E2 BEIGE PEARL CS., 4R2
Then as a second check to verify I had the correct part, I plugged in all those part numbers on Lexuspartsnow.com using my VIN, and the only one that it showed was a correct match, was the "75850-60010-B0 GRAY ME., 6T2 , 8P6". Kinda convoluted way to figure it out I guess, but I'm confident it is correct. I also have the luxury of decoding my VIN on the Club Lexus forum at
VIN Decoder - Club Lexus Forums, while that one won't tell me my exact colors (not that I could find anyway), it tells me all the names of the possible colors for that year.
Black Onyx - (Black) - 202
Blizzard Pearl - (White) - 070
Blue Vapor Metallic - (Blue) - 8P6
Eucalyptus Mica - (Gray) - 6T2
Galactic Gray Mica - (Gray) - 1E9
Sand Dollar Pearl - (Gold) - 4R2
FWIW, I haven't ordered this replacement panel yet cause it is about $350 plus shipping and I'm not so sure mine is really in that bad of shape... heh
