What did they use for drive shaft set ups? Mine is the 128" wheel base v8, 3speed manual. Looking under the truck it doesn't apear it was a 2 piece driveshaft with hanger bearing as I can't see any evidence of a hanger support mount etc. From tail shaft to the diff yoke is 67.5"

Also what did they use for a trans mount or cross member for the frame as mine doesn't have one of those either but you can see the tail housing is casted for a support mount.

 

Flange made as part of extension housing: Trans mount bolts to flange then to cross member on Passenger Cars, 1965/66 F100/250 2WD, 1966 F100 4WD, 1967 and later F100/350.

1961/64 F100/700 is different: Bell housing (7505) has two ears. Two rubber insulators (6A061 lower & 6068 upper) used per side...as you can see in parts catalog pic.

Oh so in this particular truck application there is no support cross member for the rear extension housing of the trans. It does have the big cross member and rubber mounts that runs under the bell housing like in the pic.
