Hey guysSo I have a 71 f100
but every 71 f100 I've seen online they all have the gas tanks in the cab, mine is under the bed , and my bed has a utility box on the passenger, I figured the bed was swapped from an f250 mabey, although there is no evidence that a gas tank was ever in the cab , my seat pulls down and there is a bone stock compartment , and I stripped the paint and where the gas cap was supposed to be is solid steel no Bondo .
I'm completely puzzled

 

Some pictures might be a help.

 

Welcome. Pics.

 

And while you’re at it, what is the VIN and what do the certification label on the B-pillar and warranty plate on the door say?

 

Could have been optioned that way:

Was just thinking just the same thing about not having an in-cab tank, but didn’t realize it was an optional thing.
Because the half tons had the wider frame I thought they got the underbody tanks sooner than the 250s with their narrower frame did.
But with so many changes over those few years, I can’t keep track of anything in my mind anymore.

 

You are thinking of 73+ having the wider frames. 67-72 F-100/250/350's had the same 33 1/2" frame width behind the cab. 73-79 F-100/150 2/4wd and 73+ F-250/350 2wds had 37 1/2" frames. 73-77 F-250 4wd's kept the narrow frame width. 77.5-79 F-250/79 F-350 4wd's got the wider frame width.

 

Thanks!
Getting my series mixed.

 

I was hoping one of you experts could help me identify year of my (deceased) brother's truck. I am thinking 69 but not entirely sure. Anybody want to weigh in? Thanks in advance

 

Grill is 68 or 69. Have a VIN from the door tag?

Thanks. Sadly no vin tag. The truck is long gone. I'm just taking a trip down memory lane. The picture was taken at my brothers wedding in 1972. Although the photo is grainy you can see me standing in the background at age 13...haha!

 

That’s a great family photo then!
