But, it should still have the "4-pinion" planet and the "4/5-plate" clutch drum. 
Scott.
True that Scott, "most" FE truck units have the 4 pin rear planet.
Some only got the 3 pin. 1/2 tons mostly.
I've never seen one with the 5 plate drum. Not saying they don't exist. Probably only in the FT units.
Not the "regular" FE light trucks.
Most have the 4 plate drum and some were built with the 3 plate.
Heck I once built a 66 T-Bird C6 that had never been touched before, and it had a 2 plate direct drum.
Up to that point I didn't know there was such a thing.
That was in the 80's and I was shocked that such a heavy car would have that.
It was "only" a 390 car... but still... a 2 plate direct drum??? what was Ford thinking.
Never seen another since...
