Decode your Protect-O-Plate Warranty card.

 

 

The Protect-O-Plate (P-O-P) was designed to be used by Chevrolet dealers to identify the owner and the vehicle.  The owner's name, address and the vehicle's delivery date was embossed on a special tape affixed to the plate.

 

The P-O-P was glued to the inside rear cover of the "1969 Chevrolet New Vehicle Warranty and Owner Protection Plan" booklet. When warranty service was performed on a customer's car the P-O-P was stamped on the work order.

 

The P-O-P was never meant to be used as documentation the way enthusiasts today use the card. Then again, the body broadcast sheets, trim build sheets, etc. weren't meant to be used either and were more often than not  discarded at the assembly plant. Likewise, the P-O-P was usually discarded when the vehicle went out of warranty or when the car was sold as warranties usually did not go to the new owner.

 

Today, the P-O-P is one of the best pieces of documentation you can have as it not only identifies the VIN but also the correct engine ID code and date of the engine, the correct transmission number and date along with the rear end gear ratio and date. Some options were also coded on the P-O-P such as power steering, power brakes, radio, air conditioning, etc.

 

The Protect-O-Plate is located inside the inside rear cover of the warranty booklet. The original stamping is a mirrored stamping, this example is from the Atlanta, GA. assembly plant.

 

Beware of reproduction (fake) Protect-O-Plates, they can make a put-together Chevelle appear to be authentic. Sellers will even put your name on authentic-looking GM tape. Apparently it's not illegal but any fake documentation is misleading to a potential buyer and, to many Chevelle owners, unethical as well.

 

This is the above Atlanta, GA. P-O-P mirrored for easy reading.

 

 

Line 1
* The complete VIN for the car.
* The "R" is for the carburetor type and in this example it is an "R" for a Rochester carburetor.

 

Line 2:
* Engine identification showing the engine plant code ("T" in this example for the Tonawanda engine plant), a 4-digit number for the day and month of the engine assembly, and a two-letter suffix code identifying the engine size/hp and transmission type. in this example the engine was assembled at the Tonawanda engine plant on November 4  (1968) and it's a 396cid 325hp engine with TH400 automatic transmission.

* The rear end ratio, date, and rear end assembly plant. in this example "CX" is a 3.07:1 gear ratio, 1028 is the assembly date of October 28 (1968) and "B" is for the Buffalo, NY. axle plant.

* The letter "N" in this example is the build month of the car, November 1968.

 

Line 3:
* The 69C223 decodes to a 1969 TH400 automatic transmission for the 1969 model year assembled on August 10 (1968). The TH400 date is a Julian date starting with the first day of the previous calendar year, 1968 here since it was destined for a 1969 Chevelle. The 223rd day of 1968 is August 10. The letter "C" is found on the tag riveted to the transmission to identify a 396cid/325hp engine.
* The number "1" in the second position indicates the car was optioned with RPO J50 power brakes; the number "3" in the third position indicates the car was optioned with either RPO U63, U69, or U79 radio equipment; the number "3" in the fourth position indicates the car was optioned with RPO J52 disc brakes.
* The bowtie emblem indicates this is a Chevrolet plate.
