We own a beautiful 1966 Oldsmobile and when purchased it came with a 1966 Oldsmobile Owner Protection Plan booklet with a metal plate attached. We can see on the metal plate the VIN number of the car but wondering how to decode the other entries on the plate. Welcome comments. Thank you.

 

A photo of your P-O-P will get you a more useful answer.

 

Thank you for your message. Appears this Protect o Plate was dealer issued as it has the date of purchase & the buyer's name on the plate.

POP Plate indicates:
Upper section::
buer's name and address 25 176 then a symbol
5 13 66 ................which we determined was the date the vehicle was purchased
Z 121675

Lower section
080 K1 VIN Number
V113495 10100
S4

Appreciate any insights into what the entries on the POP represent. THANK YOU!

 

Thank you again for your reply. 'We are new to this forum, so hoping the attachment which pictures the Protect O Plan comes through. Welcome any help in decoding the plate. Thank you.

 

 

The ones on the lower left are the trim code 080 black sport seat (buckets?) and the paint and top K-1, must be a black rag or vinyl top. K is ocean mist, which I think is blue?

V113495 is the engine production number. I think V and no suffix was 442 not tri carb.

S4 is the rear end (which was 3.08 open in 67, but I don't see that in 66)

 

Oldsmobile code K in '66 was Ocean Mist. My Toronado is code K Ocean mist. It can look slightly blue in lower light situations.

 

Thank you so very much for the insights regarding the Protect o Plate. Great information. The car is a ocean mist color (i.e. see attached photo). Also very much appreciate the information regarding the engine production number with regards to the V with no suffix being a 442 engine. Really APPRECIATE the insights.

To your knowledge, with regards to the Protect O Plate, is there any other correlations between the Protect O Plate and the vehicle besides both the VIN # on the Protect O Plate matching the VIN number on the vehcile. This vehicle had its manufacturing finalized at the Freemont California plant, so no V5 on the COWL tag. We showed the vehicle to a friend and he siad it should have a V5 on the COWL tag however he was not aware that the Fremont California plant did not add this designation on the COWL tag, so he learned something new. We also notfed on this vehicle that the BIG Block identication number is E390925 which when we researched on line we discovered documentation that this identification number corresponds to a 442 engine. To the best of our knowledge, the vehicle is a 1966 Oldsmobile Cutlass 442. Welcome your comments & please accept our thanks for taking the time to assist with your comments. Thank you.

 

Ok, so casting numbers, which is the six digits and the E, is all engines of that type. Stamped numbers are for just that engine. That protectoplate needs to stay with the title for the car. It ties the vin of the car to the engine (or, at least, that head) and maybe the trans. This is the only way an Olds pre-68 can match its numbers, the engine and the vin on the car match the protectoplate.

To recap, your tag has:
The original owner's info on the upper left.

On the upper right it has the dealer code 25-176. That is: Carmichael Oldsmobile INC Beaverton Oregon.
It also has the date of sale May 13 66 and the back part of the VIN.

On the bottom left, we have discussed this already: Trim, Paint, Engine ID, and rear end.

On the bottom right, full vin, and that is probably the Fremont body number, which means nothing other than the order it was built.

Your Fremont cowl tag will confirm body style, month and week of production, body number, paint and trim. Most of this you already know. Fremont cars do not use the accessory codes.

That is all that protectoplate has, and it is enough. Enjoy the car, keep the plate with the title.

 

You can also tell your friend that FREMONT cars are the most commonly faked 442's because they didn't use the proper symbols on the cowl tag.

The 390925 E number is actually a casting number that shows its correct for 1966-67. On this site they are commonly referred to as "E" blocks to differentiate between the 1965 "B" block 400 (casting # 389298 B) and the 1968-69 400 (casting #396026 G).

 

Hello Koda,

This is so very helpful. THANK YOU so very much! APPRECIATE your extra efforts.

 

Thank you so very much for the insights. Appreciate your help. Thank you.

 

The 10100 on your Protecto Plate are option codes. I have attached the list from the 1967 Product Information Manual as I do not have the 1966 PIM, but they should be the same. The 10100 indicates Cruise Control and Deluxe Radio.

 

Can i please decode options code 32111 from my POP - Oldsmobile Delta 88 Holiday Coupe 1966

3 Power steering and Power brakes
2 AM-FM radio
1 Aircondition

?

Thanks
