Good added info, AK (as always). 
Now that the truck is not doing daily duty, I don't know how much more I'll sink into it for mods, but I'm definitely going to keep this in mind if I start finding myself in off-road/muddy surroundings more often.
P.S. The front liner extensions I fabbed up sure have kept the crud out from behind the bumper and off the horns and fogs.

I have to get some blood enzyme test every week for a month but that's it for now.

LOL... yep. Fixin' on getting under the hood for a bit this weekend. She's a little bit disabled right now.... I stole a bracket off of it to make the 88 accessory drive work.
By the way, I took the 88 out for a jaunt tonight and it ran really well. Between fixing the vaccum leak in the EGR valve and putting a little Kroil on the distributor bushing/bearing, it's the happiest I've felt it.

AK, or anyone who might know the answer to this but I start with AK because of his yard experience. In the 50's and early 60's some of the "work" vehicles that weren't 4WD offered a reduction gear transfer case type device. It had nothing to do with the hubs. Do you know what they were called? Searching with reduction gear and RWD transfer case doesn't come up with it. I had a 62' International Travelall that had one. In high it operated as a 1:1 pass through for the manual transmission and in low it was something like 1:1.8 ratio. 1st and 2nd gear were creepers topping out at maybe 3 and 10mph and 3rd and 4th were fairly normal except very slow but lots of power. Top speed in low was 35 to 40 MPH. Looking up Travelall options just leads to Travelalls for sale. Under the rear seat it also had one of those school bus type heaters options that got the travelall way too hot. It was also my one and only vehicle with an oil bath engine. That was interesting. ---This is just about remembering something but not being able to remember or find what the gearing option was called.
Also with my first day of being able to work legally (pure hyperbole) and thinking truck, I get to cut the grass as my first chore. lol
I also want to thank everyone for the well wishes for my sister. She leaves the critical care hospital she's been in and is going to a recovery\physical therapy hospital today where she will be for at least another month. Anyway, thanks again.

are you talking about a 2 speed rear?
my buddy's grandfather has a 48 F3 and it was optional on that. His doesn't have it, and its a slug. all it can muster is about 45 in 4th with your foot to the floor

White, if you mean a duplex drive than no, that's not it. EDIT: But I wouldn't mind getting my hands on one. 
Stubby Bob perked my interest in one.
djflllmn, in a way it could be stated as a 2 speed rear end? It was a planetary gear system between the transmission and differential. It was lever operated. Needed to be in neutral to engage and operated as a reduction gear. The effect was like going from hi to low gearing on a 4WD vehicle. It just wasn't 4WD and unlike a transfer case it was inline with the drivetrain. It's also not something I took apart to see how it worked but it was about the size of a 2 pound coffee can and I'm guessing it had a splined shaft in it and when not engaged it did nothing but when engaged by the lever it somehow changed position on the splined shaft and engaged the planetary gear set.
Similar to this but not for a 4WD transfer case.

BTW, I did try looking up underdrive but got nowhere with that either. Ever had one of those things that don't really matter but irks you all day anyway?
