1973 Muncie Transmission Part Number Metal Tag

[Jimmy P.]

Are there any original 73 owners with a manual transmission who can verify as to whether or not the metal part number tag is attached to one of the lower tranny case bolts as called out in the 73-74 Judging Guide?
The part numbers are:
6271516 for the M20
6271518 for the M21
These numbers were the same for the 72 which also included a third 6271517 for the M22.
The numbers were also followed by a two letter broadcast code. For example the two letter broadcast code for my car is WD (found on my Buildsheet). These original tags are rather pricey on line and I would like to know for sure if they were indeed present on all 73 Muncies or did this practice end with the 72.
Attached two original tag photos below.
On page 294 in the 1973 AIM the part numbers are incorrectly listed as just the opposite as I have noted above

Hope you read this Lyle C. and Joe L.
I found this thread in the archives about the metal tag from February of 2003. per our PM this may help answer both yours and my question as to whether or not the 73 had the metal part number tag present on the transmission. It may also comfirm that the 73 AIM has the part numbers reversed for the two transmissions. Thank both of you for your responses to my PMs.
Regards,
Jimmy

This anecdotal collection of tag nuggets is worthy of a Corvette Restorer article. Its also a good way to reach out to the membership, most of which who are not plugged into the TDB and ask for more data.

The downside is right now, the Restorer is running about 36 months to get an article into print!

Tom,
Appreciate your input.
I agree, could be something to pursue. This may be another result of the change GM made in changing from the Corvette Order Copy style to the 73' Buildsheet/Manifest document used for calling out parts. I just find it hard to believe that Muncie used the tags on early corvettes and other GM muscle cars like the Camaro, GTO, Trans AM etc.up thru 1972 and just stopped with the 73 But then again, I've learned that stranger things have happened. The 73-74 Corvette Muncie part number tags are included on the lists that I've been able to find. I do think they might have been present on some 73-74 cars. It might also be that there were only two choices of trannys available starting in 72 because the M22 HD Muncie was no longer used on Corvette. Another thought could be that Corvette stopped using Muncies sometime during the 74 run and started using the Borg Warner 4 speeds.
Hey, maybe they just ran out of the tags!

Hi Jimmy. I am the original owner of 73 Coupe #23440. It is an L48 4 speed with A/C. It does not have any tag on the trans side cover. The only part bolted to the side cover is the back up light switch. The car has 26,xxx miles has the original clutch , shifter, exhaust, and THE original Firestone 500 tires in storage. I am saying this to show that noone has removed or changed anything on this car. Let me know if I can answer any other questions. Thanks Curt

Curt,
Thank you very much for your reply. That's what I was hoping to hear. The tag is not present on my original transmission either. Nor is it present on other original owner 73's that I've contacted. I think it is safe to say that the part number tags were not present on the 73 Muncies as called out in the Judging Manual. Another item in the manual carried over from 72 cars, worth noting for correction in the future. What is your car's build date? I appreciate your offer for further help if needed.
Regards,
Jimmy

Hi Jimmy. Sorry I have been slow on responding to my 73's build date. It is J15 which I believe is May 15. Seems right because I was driving it for the first time on Memorial Day weekend. Thanks Curt

Thanks Curt,
Your car was built a couple weeks after mine. Nice to know of another original 73 owner. I appreciate your offer for future help. Nice to know when original part questions come up in restoration, just like this particular one.

I'm the original owner of a 73 and it never had a tag on the tranny either
