do 70's f250s have the same radius arm set up as f100s or f150s? are they interchangable?

I don't think any four wheel drive F250's came with radius arms all the f150 EB and f100 radius arms are the same with the exception of swaybar mount points and a cotter pin hole on the frame end of the arm.

all right thank you i wasnt too sure about it i guess the radius arms are kind of like the links in the suspension to hold the axle in place i guess.

They're sort of the same...the spacing on the holes for mounting the coil cup are different though, between the EB and the others.

Hey coby,
do you think you could tell me how they are different?

really I have a arm on my bronco that I picked up randomly at a wrecking yard it was laying in the import car section. it had the same hole spacing as an EB arm I have no clue what it came from but I know that yard didn't have an EB for at least 5 years before that. I guess I am just lucky. When it comes to radius arms nobody would know better than Coby.

Sure...see this quote above:

........
The EB hole spacing is tighter, at about 1" center to center, and the other arms (including 78/79 bronco) have wider spacing. I forget the exact spacing; maybe someone else can confirm. I think it's 2".

It's not a big deal...you can always redrill a coil perch.
