82 F100 rear axle code
Well I bought my friends 82 F100 short bed. Was the short bed option a lower volume production number then long beds. Don't see hardly any around in my area. Only 3 in my city (thats the 80 to 86 style) that I remember seeing .
Does anyone know what the rear axle code 075 stands for? It's a 9" rear end but wanting to know the ratio. It has a tag on it but it's covered in dirt and grime. Won't get the truck until sunday sometime. The pinion bearing is shot in it, I have another rear end but not sure if the spline pattern and ratio is the same.

It has one but it's covered in dirt and grime and I don't have the truck yet. Should have it some time Sunday. i'll clean it off and see what it says.
Did any of the 2wd 9" rear ends have limited slip options?

When you get the tag cleaned off, if it has a "L" in the numbers you have a limited slip. I don't know if it was an official option or not, but I don't see why they would not have had it as an option.

In 1981, according to my shop manual, your rear axle is a code 07 = Ford 2800 lb. capacity 2.47 ratio. The 5 would represent the front axle, and the only thing they have listed in this book is a code of 2 (which means Front Axle Limited Slip).

You were correct. After cleaning off the tag it shows 2_47 as the gear ratio. That seems geared kinda high. The pinion bearing is shot (has a lot of slop in it, and I don't mean backlash). I have another 9' rear that is good but has 2.75 gears.
I plan on putting a 4 speed that is a OD 4th gear in to replace the standard 3 speed that is in it. Does 2.75 sound to high, I thought it would be more like 3.00 to 3.50?

Mine is a 82, F100.
That truck was sold as a light duty high mpg truck.
I have a 4-speed with OD and wanted a little more low end and picked up a ring and pinion on e-bay for $100 and $125 to have it installed and a new seal. I went with something around 3.05 or so, cannot remember for sure.

He's giving you a TOD, which is an aluminum-cased Tremec gearbox with a top-mounted shifter. You're going to need to cut a hole in your floor to fit that, even if you already have a floor shifter, which I'm assuming you don't. It's not going to have much in the way of low end acceleration, but it will get pretty good gas mileage. You can swap in that 9" 2.75 carrier without too much work if you want. Your 9" and the one in the truck should both have 28-spline axles.

I already have 2 newprocess trans. The bad part with that is that you have to use a 2 piece driveshaft. There isn't any place around here that I know of that can cut and balance a drive shaft.
Would a t5 trans work? I don't really plan on doing a lot of hauling or pulling.
The 2.47 or 2.75 rear gears would do pretty good for highway but not as good for in town would it? Most of my driving is in town.
I don't have any problems cutting a hole for the shifter if I need to.
I got some time to think about it before I have to decide. I have to fix the rear pinion problem and the brakes are next to nothing. The gas tank has to be replaced and the fuel line also. The old tank had a ton of rust and gunky old gas in it. Plugged up the fuel line in tank and on the rail. Figure it is just best to replace it and not worry about getting stuff in the new carb.
