MUNCIE METAL TAGS

[427king]

Can anyone tell me where i can find nfo for decoding metal 4 speed tags for muncie m20 21 and 22. I have 40 or 50 of those metal tags from mostly 69 and 1970 and would like to decipher some of them.

3950356 is for RPO M20 with L48, L34, L35, LM1
3946797 is for RPO M20 with Z28 & L78
3946798 is for RPO M21 with Z28 and L78
3950318 is for RPO m22 with Z28 and L78

I believe this info is according to the AIM for 1969 models.

Lots of people contributed,but credit goes to Chuck Hanson for publishing this all in last months Chevelle World.Box #28 on the Buildsheet will reflect the 2 letter code as well.

Thanks.

In the past 6 months or so I've had several 1969 Chevelle people asking me for tag #3946767 for an L-78 application... I don't have this tag and have never seen one... If you go to Camaro assembly manual the tag for L-78 is 3946797... My question is does anyone have a 3946767 tag, or have they seen one??? Or my thought is that it's a typo and the 9 got flipped in the printing process to become a 6... These tags are usually in familyies of tag numbers...
3946797
3946798
3946799
I have never seen any tag number either side of 3946767...
I'm open to any and all input... Crash

Hate to say, but Chuck's list has several errors in it. Also, note that Chevelle and Camaro shared some applications, but some were unique.

Crash,
The 767 # is one of the errors.
