My 54 is a true Heinz 57 so I don't know the year of this transmission--diff is a 51. Following the instructions in the shop manual I have slid the drive shaft yoke back as far as I can, and it now rests on the transmission case. Note--the bell is back as far as it will go. My sense is that using a pry bar I can slide the yoke back farther allowing the torque tube to drop. (It is supported so the drop will be short and controlled). Am I correct? Unrelated, but note the guide pin at the top of the transmission is a 4" bolt. Is that long enough?
