Where to find data plate decoder?

[Vipassana]

Trying to find a list of data codes for a 1966 Pontiac Bonneville. I've found a site that has the codes for a 1965 Catalina, and while some of them are similar...there's still codes I have, that aren't on there; so I need one specific for this vehicle.

Or, if anyone knows what these codes are? This is the left side of the plate:
12B1
66-26239 (I know this one specifies 66 Bonneville, 4-door)
Trim: 551-A
EXYS: 2KZTV
4F


On the right side, it lists:
6102 Body
H-2 Paint (I believe this means Palmetto Green Metallic, black vinyl top)
3B
9-2.


Any help?

Thanks!
