Oh - those numbers on the side of it....

On the tailshaft: 3911984 GM 5
On the non-bolted plate side: GM 2 E271 8987948 (B987948? 3987948?)
On bolted plate side: GM2 3952648 E271
Tag on bolted plate side: 3968081QY (396808IQY?)

And one last tidbit of info: This SOB was wound the hell out in 3rd gear when hooked up to my 3-on-tree. I could only do 65 with it running 5k RPM at 65mph with my 3.73 gears. I hope this helps?

All the numbers I am looking up online keep saying this is a Muncie 4spd, but ... I don't believe it.

Would the shift linkage linkage have prevented me from hitting the 4th speed?
