Rear end swap
There is a very informative article in the 1948- 60 forum about swapping out the rear axle in those trucks to a 1957- 72 F100 rear end. I have a 1946 ford 1/2 ton.My question is will the 1957-72 F100 rear ends work on a 1946 ford 1/2 ton pick up. Not sure if spring perches and pinion angle will be right or if axle hub to hub measurement will be OK. Any one have any info?

These 9" are not that uncommon. I got one when I called a guy about flathead motor in a car he was parting out. When I found out that he had a bunch of cars I asked about a '68-'72 F100 and sure enough he had one and he had already pulled the rear out. He is a dirt track racer and him and his buddies grab all the 9" they can. He sold it to me cheap ($80), then when we were throwing it in my trailer, he pointed at it and said "you just got a really good deal" as he pointed to the big N on the center section. He didn't expect that to be in an F100 and didn't back out of the deal :-)
I then bought a '57 when a guy in N MN listed it for sale for $50 I really liked the round back of the case on the old one.
Then about a month later I bought a stock banjo from a guy putting a Chevy in a '47 for $50.
So I have choices :-) As rusthunter suggested watch the ads for parts trucks. As you are out looking for other parts it never hurts to ask. Know the measurements you are looking for, like me you might find someone with a pile of them and you have to sort through it to find the one you are looking for.

That is a question that I don't have enough info to answer. Someone else might already know. The '57-'72 F100 is about 61" wheel mounting surface to wheel mounting surface. The spring spacing is about 40" on center. Does the '40 one ton have parallel leaf springs? I know the 1/2 ton used the car frame with a single spring.

1940 springs
hi,
thanks for the reply,
yes, the 1940 one ton has leaf springs, very long, about 10 leaves in each....
I will have to take a few measurements to see exactly what I have,
thx,
