Nice find, this truck is set up 10 years ahead of its time, not just the auto and power steering, you have the solid wheels as well ). A keeper! The Dana 60 was available with higher gears in the late 60's and 70's, a rear end shop should be able to install a 3.73 or ( 3.54 for flater terrain ) for higher road speeds.
Thank You! Reluctant to change anything - like to keep it as original as possible. Thing is low-geared though. We both happy cruising in the neighborhood of 50mph!
I understand on keeping things original, just a thought. However, you have a vehicle with no axle code, which means you could technically swap to a higher ratio. The omitted axle code or DSO code could stand for limited slip rear axle or different ratio, if they were not a standard options in '59.
Thanks again TripleFrame! Received an explanation about the 'blank' axle code on plate being a DSO. Also understand these DSO records are unavailable. That being said, is there an easy (or difficult!) way of determining and ID-ing what I have here in regards to the axle and anything else that may have been a part of that specific 'DSO'?
Unfortunately there are no permanent records on the vehicle, only the original owner and selling dealer
knows exactly what was ordered that was not a regular option. It could be a heavy duty generator, more leaf springs. different axle ratio etc. The power steering, automatic, and possible locking differential were regular options ( but uncommon) on '59's. ( By the way, is there a metal tag on one of the rear different cover bolts.? )
Thanks Again - a wealth of information! Wondering how I could ID the axle, ratio and the like (axle code blank). Understand no DSO records, but I should be able to ID whats there - just not sure how. Assuming its a Dana60.
Stack of leaf springs is 10 on back and 7 front - pretty stout.
Add another option to your already well optioned F 250. It appears the tag originally said "USE LIMITED SLIP DIFF FLUID ONLY" . It appears more and more your truck was ordered by an experienced truck buyer, someone who was well schooled on the type of vehicle that was necessary to perform a specific task. IMO, this truck is set up typically of the type of pickup you would see ordered around in the late 60's to make camper hauling in the outback a better experience. Unlike others who learned the hard way by mounting a heavy camper on a 6 cylinder 3 speed 1/2 ton. Only thing missing now is an air conditioning unit!
Thanks Again - much appreciated! A camper vehicle makes sense. The bed is in almost perfect condition - appears to not have been used for work directly.

Limited Slip (introduced in 1959 F100/250) would be AFAIK .. an RPO .. so there wouldn't be a DSO code for it.
Of course we really don't know what rear axle was installed...unless it can be identified by the ID tag (if still present) or by doing a comparo.
The standard equipment rear axle would be the Spicer/Dana 60.
