Axle gears for original run of 36 ton shays

[Artfull Dodger]

Does anybody have a scrap set of original trucks for the first run 36 ton 2 truck shay?  I my be possibly picking one up that has 2 axles that are nolonger being driven by the motor, just freewheeling.  I do not plan to run it much, so the $250 cost to replace the whole truck with a new set off fleabay isnt really in the budget.  Just looking to restore it back to all wheel drive.  I see nothing on the parts dept unless the axle sets from the 55 ton 3 truck shay will work in the early trucks.   Thanks in advance   Mike
