AMC 1965-67 VIN (serial number) decoder

All Marlin bodies were built at the Kenosha Lake Front Plant

All Marlin Serial Number or Vehicle Identification Numbers (VIN) will be found under the hood on the passenger side of the car stamped on a plate welded on the top of the spring tower.

1965

In 1965, the first number of the seven digit number is the engine code for the car,
2=232-Six, 3 = 287 V-8, 4 = 327 V-8

The remaining six digits are the sequential serial number, starting with 100001 through 110327.
For example 3101832 would mean the following: 287 V-8 and the 1,832 car built during the model year.

NOTE: All 1965 Marlins were manufactured in the Kenosha Plants.

1966

Starting in 1966, AMC went from the 7-digit serial number or VIN to a 13-digit code as follows:
The first 7 digits told about the cars makeup and the remaining 6 digits are the sequential serial number.
For example: A6KS97W100001.

First digit	A	= Make = American Motors Corporation
Second digit	6	= Model year = 1966
Third .digit	K	= Plant of Manufacture Kenosha, Wisconsin USA
	B	= Plant of Manufacture = Brampton, Ontario Canada
Fourth digit		Transmission Type
	A	= Automatic Column Shift (3 Speed)
	C	Automatic Floor Shift (3 Speed)
	F	= Floor Shift Four Speed Manual w/console
	M	= Floor Shift Four Speed Manual w/o console
	O	= Three Speed Column Shift w/ overdrive
	S	= Three Speed Column Shift w/o overdrive
Fifth digit	9	= Body Type = 2 Door Hardtop
Sixth digit	7	= Class of body = Marlin
Seventh digit		Series and Engine = 6650 Marlin Engine Codes
	S	= 232/2V Six OHV
	T	= 287/2V V-8 OHV
	U	= 327/4V High Compression V-8 OHV
	V	=232/1VSixOHV
	W	= 327/2V Low Compression V-S OHV

Eighth through Thirteenth digit = Sequential Serial Number: Starting with 100001 for the Kenosha Plants and with 104547 for the Brampton Plants.

1967

For the 1967 model year, the thirteen digit Serial Number or VIN was continued from 1966, except for the 2nd and 7th digits.

For example, A7KM97V100001 All of the Characters remained the same, but the change in the Second digit = Model Year = 7 = 1967

And the new engine codes that became available for the model year in the Seventh digit Series and Engine - 6750 = Marlin Engine Codes

For 1967 new AMC V-8 engines were offered, the 290 and 343, replacing the old AMC 287 and 327 engines which were much heavier. The 1967 engine codes are:

S = 232/1VSixOHV

T = 232/2VSixOHV

U = 290/2V Low Comp. V-8 OHV

V = 343/2V Low Comp. V-8 OHV

W = 343/4V High Comp. V-8 OHV

X = 290/4V High Comp V-8 01W

Eighth through Thirteenth digit = Sequential Serial Number = Starting with 100001 for the Kenosha Plants and with 102545 for the Brampton Plants.
