Cowl or fire wall tag info

[quote quote=13595]Jim, my 62 had air conditioning and no stamps at all in the ACC line.

But a/c could be dealer installed and no way to tell. The assembly line manual outlines the installation, but it would take a lot of work at the dealer to install it.[/quote]

I did not see this when I ask about your cowl tag Disregard my earlier question…

Thanks Don!
Yes, this is the page and links that I lost some time ago! Great to see it again.This has cleared up two cowl tag issues for me; first, the BODY code of plant and running make number from that plant only. Second, the IBM codes that may have been used for the ACC. codes. From this quick review, I stand corrected on Eric’s parts car, it is production #98 for Jetfire’s from Lansing-very early. Now I know that the IBM code for a 4-speed manual is 384. The BC – South Gate, California plant spelled out the 4 speed manual transmission. I still am not sure about the A/C option which should be ‘N’ and I have not found that code on a plate yet. I do not know what code was used for a vinyl top code color as I have only seen a ‘1’ and all of these have been white vinyl tops. I would like to know if they used the conv’t top code of ‘2’ for a black vinyl top? Anyway, thanks for the reference to this data again Don!

I would like to find the GM document where they got the IBM code information. They had to get it from somewhere. I would just like to add that to the collection of information I have for our 4 speed car.

I did not make it to the GM Heritage center last Fall like we had planned. Work was just to crazy for me to get away. I am planning to go the first chance I have away from work. Maybe I can dig up some of this information.

Jim, does the A/C have anything special that needed done by Fisher body plant? I know they needed some holes drilled but that would have likely been done during the final assembly and not by Fisher. If Fisher body plant don’t have to do anything special to the body then I don’t think it would be on the tag. This would also make since for the 4-S transmission to not be on there. All the floors were for automatic so nothing special needed done to the floor. They had to be cut and a 3 speed hump or a 4 speed hump installed. Makes since that the 3 and 4 speed each have there own code if the hump is not the same between them.

Not sure if there is any truth to this but I was told by a guy that worked at a dealer back then that many of the A/C f-85 models came with most of the A/C parts in the trunk and the dealer had to install them. Is there any truth to this?

2M is not A/C because the 63 we sold had M2 on the tag and was not an A/C car

Does anyone have a picture of the cowl tag for the $50K Mecum car? I took several pictures of that car and I can’t believe I did not take any of the cowl tag.

Where were the floor pans modified for the 4 speed trans tunnel? Was it at Fisher Body or at Oldsmobile? Hard to believe Fisher would do the trans tunnel mod that way.

I believe it had to be done at Fisher. All the clutch linkage mounting holes and firewall would be the same between 3 and 4 speed but going buy the IBM code, both have there own code on the Fisher cowl tag. The only difference in the body between the two is the floor hump. If Oldsmobile was doing it I do not believe it would have been on the cowl tag.

I would like to see the 3 speed Jetfire cowl tag. I can’t remember who that was or if they would be willing to post it.

I wonder what the 2M code in the ACC line of my ’63 Cutlass tag and Eric’s ’63 Jetfire tag means? It doesn’t correspond to any of the codes I’ve seen. I have several options on my car but the major ones are automatic transmission, air conditioning, power brakes and power steering. The holes in the fire wall for the air conditioning lines look like an afterthought but I have no way of knowing if they were made at the Fisher Body Plant, at the Oldsmobile Assembly Plant or at the dealership. I wonder what Eric’s car and mine have in common for the 2M code?

[jensenracing77]

The one we had did not have power brakes or A/C but it did have automatic and power steering. One of our 62’s has power steering and the other does not and neither of them have the 2M but maybe the 2M is a 63 only code? I don’t believe the power steering could be it.
