Okay, So the Dynaflow was done after 63.
The 64 ST transmissions were junk. (so I'm told)
In 65 and 66, the ST 300 was made in both, BOP, and Nailhead, patterns??
Were they the same transmission on the inside? Or, was the Nailhead patterened one, built with different internals to handle the torque of the Nailheads??
Also, was the ST 400 also made in both patterns, as well??
Also, does someone make a Nailhead adapter for the TH400, or the 700R4??
I saw one for the 4L60E, but I'm not interested in a computer controlled transmission.
Thank you.
