Transmission adapter to mate a slant six to a smallbock trans
FYI
There were 2 different crank spacers, depending on the year of the transmission, and torque converter being used.
Depends on the diameter of the "snout" of the converter, to the crankshaft.
So be aware of that, if your not, already.
Also.
I too have an adapter, but no crank spacer.
