Can someone please help me, I just rencently purchased a 65 rivi and need help decoding the cowl tag.

The numbers are:

65-49447 FB 93205
618 DD *
EXTS-2KR-3T-4F-5W

Diablo, the numbers read as follows-
65= model year
4= Buick division
94= Riviera series
47= 2 dr. coupe hardtop
FB= Flint assembly plant
93205= body serial number
618= interior trim color and material (sorry cannot decode this one)
D= paint color- Astro blue poly

The others are codes for options which I can't decode.
