Radius arms

good evening,
I'm going to put the front suspension from a 1975 f150 under our 65 f100.
I have everything but the radius arms, will the ones off the 65 work?
It's a two wheel drive
Thanks

Suggest call couple auto part supplier's and see what their catalog indicates. Replaced mine many years ago with the front disc. upgrade and seem to recall replacing with 66 radius arm bushing. Approx.a month ago replaced the radius arm bushings and had similar discussion with 2-3 auto part supplier's. I took the original bushing for comparison and after several miles each came up with the same bushings whether I asked for 66, or 75 bushings.

Suggest thoroughly inspect the current bushings for wear, as you are probly well aware, replacing can be labor intensive and you do not want to have to replace sooner than necessary. If the front and rear washers and nut are okay, don't want to go back for redo considering the bushing should not cost more than $15? Also, make sure to follow the torque spec's, important when it comes to alignment. Anyhow, food for thought?

The front (C5TZ-3B203-C) & rear (C5TZ-3B203-B) radius arm insulators (bushings) are the same: 1965/75 F100/250 & 1967/75 F350. Also same as 1969/74 E100/300 & 1975/79 E100/350.

I believe he's referring to the radius arms, not the bushings.

yup...I meant that ssandirene's initial query was whether the 65 radius arms could be used with the 75 suspension. I'm curious as well.

Sorry, yet again miss read the questions 'whether the 66 radius arm will work with the 75 application', I did use the original 65 radius arms when I upgraded to the 75 front disc brakes. Sorry, perhaps my comments will help should it come down in deciding on radius arm bushings?
