'hoghead' ?

[hardtimes]

Awhile back , I got a 4 speed trans out of a rodded A pickup. Complete with what is known as a hogshead bellhousing. As fate would have it, just got a 3 speed trans out of a rodded A pickup. Bell looks same/same on both.
My inquiry is ...did Ford put 3 and 4 speed trans in A pickup and did both have hoghead bells ?

Attached are some pictures of the two mentioned A transmissions. I was wrong in stating that the two bell housings are SAME ! Four speed bell is near 5" deep and three speed bell is near 6 1/2" deep. Throwout bearings are different with four speed looking larger/stronger size and four speed is attached with SIX large bolts, whereas three speed is attached with four bolts. However, they both have same holes / pattern for attaching to flywheel cover.
My question now is ....can either or both of these bell housings be used on A and/or B engines ? And, which if any is 'hogshead' ?
