Buyig a 4spd trans

SO.... I went and saw the fellow with the trans.. but i found out it came from his 74 Cuda with a 318. And when i eyed it over i counldnt find the production numbers.. all i found was:
on the tail shaft C-99127

4
on casing c 97372

c 95664 Z
[3] [11-9]

This wont be an abody right? the 74 cuda was the last E body cuda. So i assume this trans wnt work.. right?

Sorry for all teh questions guys..
