or you could find a 48/53 tranny/torque tube. I see them on craigs all the time when guys convert to a open drive line. it wouldn't be "correct" for the 47 if your worried about having a 47 with 47 only components, i.e. 216 with a selector tranny/ 6 volt generator, knee-lever shocks , but would fit right?

im not sure if the 54/55 1st will fit, i think these are a different length. maybe someone else could chime in on this???

i see the trannys and rears/torque tubes on craigs all the time from guys who converted to a open drive line.
