I'm not sure if any of the BW trannys did, but if your crank is a 58 the early ones had to. I know that by 62 all the crank flanges were flat and would take either manual or auto trans. I suspect only 58-59 had the different crankshaft, but can't say for sure.

Well I have an early 232 (1970) on blocks here to compare;
and the new '58 motor has to come apart anyways. I also know
that the old six (small) flywheel I have laying around fits
the 1963 195.6OHV because I intentionally test-fit it for the
knowledge! So I know that if I make that part fit the '58 new
block I'm all set.

Since the OD of the '58 auto crank flange nose is smaller, a
simple adapter ring would solve flywheel fit; but the question is
pilot bushing hole depth and bore, and I have a bell and trans to
test THAT, so if machining is necessary on the '58 crank it can
be made very straightforward (even if this description is not :-)
