Then you actually have an NP420 according to what others have provided along with VPW's catalog.
Your bell housing# 9211982
FFPW - 47 to early 56 (serial# 83949001) bell housing# 921197, after serial# 83949001 1666520
WC 3/4/1.5 bell housing# 921197
M37 51-54 bell housing# 1269428
M601 bell housing# 1786131
The housing that Dave sent is actually an NP420 housing that is why everything from your other transmission worked. The PTO 12533 that Dave sent is for an NP420 transmission. Your bell housing is not a FFPW or Military housing and is probably from a B series or other Dodge truck that used the NP420. So you don't have NP420 mounted to the 921197 bell housing.
