I pass it several time a week, looks like maybe a 54-55? Little rough, but not a basket case.
If anyone is interested I will stop and get some pix and details.

 

this may be a dumb question steve but how do you tell its a 3/4 ton truck?

 

start with the wheels ,8 bolt is 3/4 or 1 ton and what looks like (to me)a full floating hub on the rear axle.

the box will be about 4 inches taller and longer by about 8 inches(i think),then if you can see the emblems-f2 or f3would be a dead give away.

im sure there is more,once you start to find little things you will pick them out with just one quick look.

 

I was going by the F2 emblem...
