Hi Josh,
I can confirm that the VIN will be stamped on the top of the transmission housing. I have a 67 GS 4 speed and that is where mine is. Good luck!
3885010 is the casting number for 1965-1967.
P7M26
P = Muncie
7 = 1967 model year
M = August
26 = 26th
(built August 26th 1966 for 1967 model year)
Most of the numbers I've seen have been stamped on the sides.

Hey guys. I know it's been a while since I posted this thread, but I've found some new info on this topic & im wondering if what I have is good enough supporting documentation to prove this to be a 4 speed car. I have the protect o plate for the car with the date code P7M26 for a Muncie on it & the 4 speed Muncie on the car has the P7M26 stamped on it. Will this be proof enough for 4 speed documentation?
Heres res a pic of the protection plate. Maybe I can get some help on deciding some if the numbers on this.
Thanks
Josh

WOW!!!! Thanks Buford. This is great info. Are we able to access all of this info in this site? Also I was able to find some pieces if a tag that was under the back seat that had been turned into pieces of a rats nest. Unfortunately after hours of sifting through a stinking mess of rat crap & whatever else was in there, plus the added time of piecing together an incomplete jigsaw puzzle this is all I could come up with. Any ideas on what kind of tag this is & what some of the numbers might mean. If you do know what tag it is do you have a similar example do I can see what I'm looking at?
thanks again for all the great info.
Josh
I also forgot to ask this, but did 1967 Buick GS 400 come with a M22 Muncie Rick crusher??? If so are there any exterior markings to signify this or will I have to pull the trans & look at the gears?
thanks again,
Josh
That looks like the broadcast sheet. Best pic I have is one from 1965. I don't think the POP decoding info is available online, just from years of collecting data. More trans info here:
