I have an automatic transmission that my son took from a '67 or '68 F100.  It was behind either a 351M or 400M.  I'm pretty sure the engine was replaced in the truck and the guy my son got it from said he thought the transmission was from the same car the engine came from.  It looks like an FMX, has the same bolt pattern to the bellhousing as an FMX that I have, but the tailshaft is about 3 1/2" longer than the FMX.  The torque converter has a notch cut into each side of the snout that goes into the pump instead of flats.  There is no tag to get any numbers from, but the case has D8ZP-7006-AA.  It looks like an FMX with a long tailshaft.  Could it be a cruise-o-matic?  If so, would it be a 3 speed?
