I think there's a label on the driver's side door opening that has a rearend code (at least on an '81).

That code would most likely give you the info you need.

Just post that code and someone will most likely have the info.

You're missing the first numbers on the left hand side. But, I can tell you that you have a 3.50 geared 9", 3.50 is the only factory 9" ratio that ends in 50.

I attempted to read the tag on mine in darkness, using flashlight. It's weathered a bit since '81. I'll clean the tag off in AM and give it a better look.
350 ratio, 4 speed tranny, 351 engine, and a light weight truck should give me fairly respectable gas mileage.
My '81 F150 stepside shortbox is my baby that will only be allowed outside when the weather is nice and the roads are dry. Same goes for my '86 F350 crewcab dually - I have younger trucks to do the serious work. My Old Dually is only allowed out to play when the road is good.
Fords Forever!

Welcome to FTE

Ford = Flareside, a stepside is a (gasp) Chevrolet.
