The VIN tag is on the metal dash, at the lower drivers side corner of the windshield.

This body tag decodes as follows:

CK31403

C - Chevrolet nameplate
K - 4wd
314 - long wheel base cab chassis
03 - pick up variant

ZY1 - solid (one color) paint
L05 - 5.7L small block chevy V8 engine (fuel injected)
ZW9 - base body (cab chassis)
DG5 - west coast style mirror option

The numbers across the top may be some "in process" build sequence numbers, perhaps through cab shop or final line

I don't recognize "FLR" but it is in the RPO format.

"97" when coupled with a "U" (ie, 97U) becomes the exterior paint code: Dark Gray Metallic . I don't know what the 07 would be.

Is your truck a carryover R/V truck (like mine) or the "new" GMT400 version?
