Radius Arm Interchange
Greetings,
I spent a good deal of time searching for this subject before posting, and if it's a repeat question, I sincerely apologize.
I own a 1977 F100 2wd Flareside with a 351M. In preparation of radius arm bushing replacement, I noticed that my right side radius arm has a slight upward bend. I used to do alignment work, and know that back in the day it was not uncommon to bend the radius arm slightly to correctly set caster angle (although I personally never did it, my boss would occasionally do so for customers).
Short story long. If in fact, this is not a intended bend and I must replace it, I am curious if the radius arms from a 2wd F250 will interchange?
My suspicion is that it won't as I have learned (from this forum) that F100 and F150 will interchange, but no mention of F250.
Any ideas? Any help will be very much appreciated.
Take care,
Jesse

Thank you for the reply. I was looking at them at the junkyard today, and visually there seems to be no difference, but I wasn't sure. Only 73-79 trucks in the local u pull it are F250 2wd. I would rather buy from them if possible.
Thanks again,
Jesse

Two things to consider without consulting an MPC
I would replace as a pair to match up any differences not visible to the naked eye
The F250 had around three GVWs and the lowest rated F250 did share some brake/suspension parts with the F100/150
If Mike or NumberDummy or a couple of others have more concise info..
