I believe I stumbled upon a '68 or '69 Belvedere...

Trim tag is as follows:
20139 228095 9A227130
925 593 603

1T 6W
F5 F5 H2T T7 (sideways O)
RM23 E63 D21 214 B40645
.

TOP LINE:

20 = gate and 139 = base numbers. These are related to the production of the body in white for that car.

228095= Sequence number. Number of bodies produced during that model year at that plant. (take this number and subtract 100001) so this was body in white # 128094

9 = 1969 model year
A= assembly plant = Lynch Road
227130 = VIN number

1T= V1T = Tan vinyl top
6W = V6W = white sport stripe

925 = engine assembly number = 383-4bbl for manual transmission B body. 335 horsepower. This number DOES tell you the HP rating.

593 = rear end assembly = 69 B body 8.75 rear end with 3.23 open (non sure grip) 11" drum brakes

603 = transmission assembly = 69 B body 383-4bbl four speed


F5 F5 = top and bottom of car painted Limelight Metallic green
H2T = interior trim code = High trim level, vinyl bench seat; saddle tan
T7 = inner upper door frames pained tan to match interior
(sideways O) = typical Lynch Road inspection stamp

RM23 = Road Runner Hard top
E63 = 383-4bbl (Does NOT tell you horsepower rating only that the engine is a 383-4bbl)
D21 = four speed
214 = scheduled production date of February 14, 1969
B40645 = Vehicle Order Number (VON). B indicates it was sold in Canada. So this car would NOT be accounted for in the white book production number breakdowns
