I happen to have a Daganham 4-speed transmission, Flywheel, steering column (4 speed on the column) and linkage for an early Econoline. I originally intended to put it into a '62 Econoline Pickup I was restoring but the the truck was destroyed in a fire before I got around to it.
All equipment is unrestored, but I personally pulled it out of an Econoline which was roadworthy and being driven until the day it went to the wrecking yard.
My Dad had one in his old '62 Econoline back in the '70's. I can tell you this much, when he swapped out the original 3spd for the 4 spd, it made a HUGE difference in making the most out of the 170's power. Anyone who has an old Econoline should jump on this setup, of course I don't know what parts availability is like since they are quite rare.
I have a 200ci in the van with 3sp iv'e already made a floor shifter set-up that has been in the van for 35yrs & never had a problem , so converting to 4sp l not a problem , the only problem is finding one ! there pretty rare > thanks
