Just to sort out the "yes they did" and "no they didn't"
issue. There were 2 questions asked (three if you include
materials).
1) Did Ford make a bell housing that would mate with the five
bolt and the 6 bolt block with no modifications or adapters.
(Re-read this - it is discussing the block end of the bell
housing)
Answer - NO.
2) Did Ford make a 6 bolt bell housing that would mate with
both a early 4 bolt transmission (Tiger MkI, IA).
Answer - YES, sort-of. The bell housing had two sets of 4
hole bolt patterns, backed by reinforcing material, that would
accept either transmission - EXCEPT, the central hole that the
cast iron transmission nose bearing support fits is larger.
This requires the older 4 bolt to have this inexpensive
slightly larger diameter nose bearing support casting
installed. Easy job.
The hard job is locating one of those bell housings, They
were only made during the transition years, between '63 and
'65, although it is rumored that they were not aluminum, but
cast iron form the truck line. I do not know if this is so,
or if they made them in both materials. Poor photographs are
available to show they existed, but answer none of the other
questions.
3) Unasked Question: "Is there anything else that can be
done?"
Yes. Many have taken the newer wide 4 bolt pattern aluminum
housings (or cast iron) and welded like material "backing
pieces" inside the bell housing at the points where the
narrower 4 bolts pattern wants to go. The back end is then
carefully drilled and tapped to the older pattern. This
allows one to build what they cannot find. This is a job for
professionals, so pay the price for a good job. BTW: You
will STILL need that wider nose piece, as above.
