Bell Housing Identification

I have a bell housing off a 1955 Ford F-100 that has the casting number: TBAA-7505-A. My question is, was this bell housing made for the 1/2 ton pickups or was it made for the 3/4 ton models? Interchangable? What other information can I learn about this bell housing? Many thanks for any help.
 
Hard to tell without a pic, but was thinking, only difference would be 3 or 4 speed pattern, and 6 cyl or V8 bellhousing pattern.
 
The lighter duty transmissions have the old Borg Warner narrow pattern used clear up into the early 60s. The 4-speed had the wide pattern for the T-98 or T-18. They used both of the ones made for the Y-blocks for a long time.
