I'm looking to get new grade 8 bolts that connect the I beam to the radius arm and coil spring. mine are seized, so I cut them out. lmc truck calls them lower spring bolt, but doesn't show the size. any help is appreciated.

I think the bolt hes talking about goes through the radius arms through the I beam with a nut to hold the assembly together then the spring, spring retainer, and nut screws down on this bolt to hold the coil spring assembly to the I beam.

Heavy sigh... where does Ford show that stuff... apparently not in Suspension... could be with axles, could be with springs, probably not with steering... *sigh*

I know how that is. Or you go to the proper section based off the number you are looking at for the part number and it says please go to section --- which then has 40 pages of charts.

I'm going to look and see I would assume it would be under suspension

So you cut it how do you get it out of the beam?
I could not even get the nuts off the 4 beams I have with my impac gun!
I am hopping the setup I have in the truck does not have to come apart for king pin replacement & spindle swap.

It took me Superwrench penetrant, an unregulated ½" air supply, heat, and patience but I got mine out, I wouldn't have cut them. Anyways... I found this in my service manual:
