Where do you guys get all of this info from? Here are the numbers off the trans I am thinking of buying::

Bell Housing
3743859
05305-1

Trans
PB8332763
C99129

Tail Shaft
C99126-2

I want to make sure it is an a body trans and small block bell housing. Thanks FABO!

Picture would go a long way... measure the front bearing retainer. Is it 5.125 OD, or 4.807 Non OD? It seems technically an a-body small block trans and bell, but they don't appear to match. An OD bell with a non OD gear box.

3743859 bell housing 10.5" small block 1975-80 A-F body "overdrive" 5.125" bearing retainer

PB is likely PP = New process
833 = type
2763 February 19, 1969

C-99126 maybe C-98126 for 1969-71 a-body

It is an overdrive bell housing......do they make adapters for this or should I just buy a new bell housing?

Where do you guys get the info for decoding all of this stuff?

I have seen them opened up to be used for OD but not the other way around. I am not sure what your best option would be, if it were me, I would get a proper bell.
The info is gathered from books, manual's, but much of it is on the net mostly scattered though.
