Having some problem to decode this car:

Trim 85-B
Paint N-1
Date 10D

ACC 1W-2M-4E-4V-5W

Any clues?

[8LUG]

PAINT N-1= N IS SUNFIRE RED, 1 IS A WHITE CONVERTIBLE TOP. TRIM 85 IS BLACK AND THE ''B'' IS BUCKET SEATS. DATE MIGHT BE APRIL 10TH.WHICH WOULD BE A FRIDAY IN 1964 ACC CODES NO CLUE.

[64 Bonnie Ragtop]

I thought that 10D means the car was assembled 4th week in October.

[johnta1]

Correct on the date code, 4th week of Oct.

1W - Tinted windshield
2M - Powerglide (?)
4E - (?)
4F - Remote outside mirror (?)
5W - Custom seatbelts w/retractors

Do you have the PHS for it?

[Peje]

Thanks for your help.No,not my car.The owner asked about the car on a Swedish car forum.He is informed about PHS.The interior is black on pictures so I assume that 85-B(black w/bucket seats are correct).

4 speed automatic in 64,or just Bonneville?

[johnta1]

The Super Hydramatic (4 speed) was a Bonneville and Star Chief I think.

The Roto Hydramatic (2 speed) was for the Cat and the GP I think.

Correct!

[8LUG]

Roto was 3 speed, powerglide was 2 speed

Exactly. Assuming it is not an export / Canadian version.

[johnta1]

I just looked at the service manual, and it shows the Roto as a 4 speed also?

It's a strange tranny.
It has a DR and DL looks like?
DR - Drive Right
DL - Drive Left

Plus a L - low.

Roto Hydro:

[stevep]

Roto is actually a 4 speed and also considered a 3 speed with a 2 stage 1st.
1964 Roto's did not have Drive Left and Drive right. Pontiac used that up to 1963 on column shift cars.

[Peje]

Anyone have complete info about the ACC codes, 2M and 4E?

[Engine-Ear]

I understand the DR to mean Dual-Range... with the arrow on each side, you have Dual Range Left and Dual Range Right.

My "expertise" is specific to the '64 A body (Tempest) but plenty of parallels to the big Pontiacs.

Keep in mind that the 5 Group Accessory Codes were coded on a Fisher Body trim manifest, the trim manifest was used by Fisher Body to guide the fabrication of the Body Assembly. In many cases, the codes did not indicate a particular option itself, it just meant that Fisher Body had to modify the base content Body Assembly for a given model (such as the Catalina Convertible) so that the option could later be installed at Final Assembly.

The codes were regurgitated on the Data Plate only at some Fisher Body Plants, others didn't bother. Only the trim manifest really mattered.

In '64, the front fender mounted remote control mirror did NOT warrant an Accessory Code on the Tempests because Fisher did not need to modify the Body Assembly to facilitate the Final Assembly install of this option.

In '65, the Tempest Remote Mirror design was changed, it became door mounted and Fisher did use the 4F code to indicate this option for the Tempest in '65.

Perhaps the front fender mounted remote mirror for the big Pontiacs DID require Fisher to make some accommodation for it in '64 and the 4F reflects that option.

If this car does have the Remote Mirror option and if perhaps the control for it is on the door, then I'd be inclined to think that is a good decode for it.

The 2M is most likely related to the auto trans option. I believe it most likely indicated that Fisher provided a floor pan cutout to accommodate whatever shifter was later installed for the auto trans option at Final Assembly.

You did not indicate where this car was built.

In '64, I do not believe Fisher Body-Pontiac coded floor pan cutouts for the Tempest as I believe the cutouts were made at Pontiac at Final Assembly. The KC & Baltimore Plants did use the 2M code in '64 for the Tempest and the explanation I use is that the floor pan cutouts must have been made on the Fisher Body side of the operation at those Plants.

Regardless, I believe that the 2M code on this car indicates it required Fisher to modify the standard build by a special floor pan cutout.

Sorry, but I do not have a good answer for the 4E code.

The only Group 4 code used in '64 for the Tempest series that I have ever seen is 4G.

This code is seen on Tempest Custom builds and I believe relates to the Décor Moldings (extra chrome trim) that set the Tempest Custom apart from the lower priced Tempest series.

It is unclear (to me) why this was necessary as I think the Décor Moldings were a standard content feature of the Tempest Custom series and normally standard content would not be coded. For example, the power top was optional for the Tempest Custom Convertible, but standard content for the Lemans Convertible. Hence, code 1D indicates the Power Top option but this code is only found on Tempest Custom Convertibles, never on the Lemans Convertible.

Regardless, I have seen the 4G on all Tempest Customs.

The 4E may be something similar for the Catalina Convertible.

Pulling the PHS for this car may yield clues as to what option is related to this code.

Any option that would have obviously required Fisher Body to modify the standard content Body Assembly would be a candidate for the 4E code.

It might conceivably be related to the bucket seats if they were not standard in the Catalina Convertible.

The 1W and 5W are very common codes and I agree with the decodes for them given here.

Assembly Plant: Pontiac,Michigan

Thanks everyone for your help and support.Best Regards Peje

1964 Catalina, Build sheet does not show 381 option anywhere. Shows bucket seats as option, Can anyone know for sure if it is a legit 2+2? Thank you Randy. Not my car.

Interesting, I also have a 64 cat convertible, built in pontiac michigan, but mine was built on the 5th week of october. Mine also has the acc codes 1W, 4E and 4V. My car does have the tinted windshield. Not sure about the 4E or 4V though. My car is a 389 with 3 on the tree manual. Skyline blue with blue tri color bench interior.

[johnta1]

Any phs on it?



Sounds like a cool car.

Perhaps the 4V is associated with the convertible part?
Any 4V's on a non-convertible cowl tag?

Also what plant is the car from?
