I’m speaking only in regards to the 64 Dodge mentioned here.
Yes, guys were doing the drops back in the day. In fact this driver built 25 transmissions specifically prepared to last longer than a standard 727 would. Chrysler made them available to factory guys and some others back in the day.
That’s cool, can’t place the guy though. We both older than dirt but you know your stuff, I will listen to ya.
