and here is why I needed to change the radius arms :-) ... got both installed this weekend, changed I beam bushings while I was at it...
Here is a test, can anyone tell which one is the bad one ? ha ha ;-)

ha ha, I thought some people would appreciate that picture
;-) we have a little more rust issues up here in northern ontario than many other states would - I undercoat every year & drive infrequently in the winter, but the truck was driven full time for many many years & has paid the price !

cutting out the studs on the radius arms was my plan B... although I can weld basic stuff I usually steer away from things that are safety related like suspensions :-) appreciate the info. though.
The bolt that holds the radius arm to the I beam (and acts as the coil spring mount) appears to be a 3/4" bolt, 7" long, at least that what my quality plastic vernier says... an 1 1/8 wrench fits on the bolt head snugly which indicates a 3/4 bolt as well - I will know for sure when I get er' apart I suppose...

Yes - but were any of the threads of the bolt hidden within the beam or radius arm once assembled? The reason for the longer bolt is so the load is placed on the shank/shoulder of the bolt rather than the threads. The threads are the weakest point of the bolt & where most failures occur. The original design seemed to be so all "mounting" or loaded portions of the beam & radius arm were against the shank of the bolt - not the threads.
