radius arm difference

just got my radius arms from georgia, these are ibeam style, looks like measurements are the same however my 68 has ibeam style radius arms and wonder if i even needed to get new ones, is it possible my 68 radius arms would have worked with the 77 front end?

I believe they would have, and I said so in your other post, but everybody seemed to ignore it.

Don't hold me to this, but I think they would fit from '65 to '79 (though there were some differences like cast vs stamped, holes for sway bar brackets, etc)

'80 - '96 also had twin i-beam suspension with similar radius arms, but the trucks were more narrow, hence the i-beams were shorter... I'm not sure if the radius arms were different or not.

Do not use the two stamped arms on the left, those are ready for the scrap bin.

You just proved me correct on what I posted on your other thread about the same front end pieces.
here is what I posted:

All years of Bumpside and 1973 F100/250 4X2 without stabilizer bar were the same.
1974 was different but was replaced by the 1975/77 F100/150 (and various F250s) ones. I believe as of 1974, they were just changed to stamped steel.
So the short answer is...yes. They should work.
