What is the Diameter of the radius arm at the rear bushings?

[reamer]

Can anyone measure the diameter? need to know if they are rusted out, and not worth bushing replacement, Looking at the rear of the arm area just after the threaded area the bushings are located.
Also what is the actual "hole" dia. on the frame mount?
Thanks

I don't have a loose one handy, but I'm sure someone will.
In the meantime, are yours at least still "linear" in shape? Or is there any necking-down where it looks like rust might have been eating away at it?

Most of the rusty ones have a concave/hourglass shape to the shank, where good ones are more straight.
But if your shank is smaller than the threaded end, even if it's evenly distributed I'd say that's rusted down and not good.

God pics?

I have a couple sets in my shop. The best one I found measures just shy of 7/8". The worst one measures just under 5/8" at its worst spot. Here are a couple pics.

I like that senior citizen tape measure. Even my bad eyes can see those numbers.

Ha! That is a Komelon mag grip tape measure. I get them at the Welding shop, it has two magnets on the end to help with metal work. They are awesome! Easy to read like you said, as well.

Well bummer. But at least you know now, rather than later. Like real later, when you're as far from home as you've ever been in the Bronco, at 3:00am coming back from a raving party, just before your wife goes into labor with your first child, and you weren't supposed to go out with your Bronco buddies because you were supposed to drive her to the doctor.
You know... "THAT" later.;D

Hah! Yep, good one.
Like when asked "Were you ever lost?" and the reply was "No sir. But I sure was a might bewildered for three days once."

If you are running large tires it would be a good time to get the Duff's T-Rex arms as they can clear a larger tire better.
