Please use this information to determine the details for your Monaro.
But if you want a Certificate of Authenticity for your Monaro, you need to call the Holden Customer Assistance Centre by phone or email custasst.holden@gm.com
The VIN is the unique identification number for the car and is recorded Nationally as the Identification of the car.
There are 4 different types of VIN tags for the Monaro;
- HK-HQ (up to the July 1971)
- HQ (July 1971 - September 1972)
- HQ-WB (1st October 1972)
- CV6 and CV8
HK-HQ
The VIN plate is located on the upper horizontal surface of the firewall in the engine bay. The VIN consists of 13 characters (letters and numbers), as per the example below.
HK
All HK Holdens are fitted with two identification plates, and have a chassis number stamped onto the firewall centre above the transmission hump. All HK series Monaros have the thin VIN plate fitted on the under bonnet cowl section in front of the passenger. Early HK Monaros had the larger Body plate fitted to the firewall, directly above the chassis number. The remainder had the body plate located on the under bonnet cowl in front of the driver.
All HK Holdens had a chassis number beginning with HK, followed by 5 numerals, and ending with letter(s) indicating the plant it was assembled in - SS (Sydney), BB (Brisbane), A (Adelaide) and M (Melbourne). For example HK23114SS. For Sydney and Brisbane cars, the second S or B is stamped below the first one and normally in a different stamp with a shallower impression.

Decoding
There are 5 sections in this number;
Section 1 First digit Vehicle Manufacturer
Section 2 Second to Fifth Digits Series Designation
Section 3 Sixth Digit Model Series
Section 4 seventh and eighth digits Assembly Plant
Section 5 ninth to thirteenth digit Vehicle Sequence Number
Section A Vehicle Manufacturer
8 = Holden
Section B Series Designation
0269 = Belmont Sedan V* (HQ SS)
0337 = Monaro (HK)*
0337 = Monaro L6 (HT/G/Q)
0437 = Monaro V8 (HT/G/Q)
0737 = Monaro GTS (HK)*
0737 = Monaro GTS L6 (HT/G/Q)
0837 = Monaro GTS V8 (HT/G/Q)
1137 = Monaro LS L6 (HQ)
1237 = Monaro LS V8 (HQ)
1837 = Monaro GTS 327 (HK)
1837 = Monaro GTS 350 (HT/G/Q)
* Note the VIN system did not differentiate between L6 and V8 engines in the HK series. Eg A 0737 designation HK series Monaro could have been fitted with either the 186S six cylinder or the 307 Chevrolet engine.
Section C Model Series
K = HK
T = HT
G = HG
Q = HQ
Section D Assembly Plant
H1, H2 = Acacia Ridge, Brisbane
H5, H6, H7 = Pagewood, Sydney
J1, J2, J3 = Dandenong, Melbourne
L1, L2 = Elizabeth Adelaide
L6 = Mosman Park, Perth
Section F Vehicle Sequence Number
The number relates directy to the vehicle sequence number for a particulat plant. When a numbe reaches 99999, the assembly plant identification code (section four) was raised by one number eg H5 chanes to H6 and the vehicle sequence number returns to zero.
HQ (July 1971 - September 1972
The VIN plate is located on the upper horizontal surface of the firewall in the engine bay.
| Example | 8- | 03- | 37- | Q- | H7- | 08182 |
| (A) | (B) | (C) | (D) | (E) | (F) |
Holden built 6 cylinder Monaro Coupe, Sydney build, build #8182
| A: | GM Divison 8 = Holden |
| B: | Luxury & Engine Size |
| C: | Body Code |
| D: | Series Code Q: HQ 7/71 |
| E: | Assembly Plant H1, H2 = Acacia Ridge, Brisbane H5, H6, H7 = Pagewood, Sydney J1, J2, J3 = Dandenong, Melbourne L1, L2 = Elizabeth Adelaide L6 = Mosman Park, Perth |
| F: | Serial Number This is the number of the car off the production line at it's identified plant |
Trim codes are the best way to ID optioned Belmont & same for HQ GTS/4
Section 4
Section 5 Vehicle Sequence Number
