Radius arm bushing rivet replacements, tack weld?
The thread about the rear spring perches got me thinking. I just got done doing radius arm bushings last weekend. I knocked out the rivets with an air hammer and put grade 8 1/2" shank hardware in, 1" long bolt, nut and lockwasher. These are the coarser 13 threads per inch. I torqued them all to 90 ft/lbs. Torquing them felt right, it didn't feel like I was going past yield but it felt like plenty to pre-stress the bolt.
I am planning on going back and re-torquing after a few hundred miles.
I don't have the Ford TSB in front of me for the rivet replacement, so my question is, should I tack weld these with my MIG after I re-torque? I don't see having to replace these for a good long time and even then grinding off the part with the tack weld will be easier than hammering out those damn rivets, but is it necessary?
Also, should I have been using flat washers also? Was 13tpi OK or should I have used the 20?

That's exactly what I was thinking, messing with the tempering, etc.
But then I saw someone mention tack welding them to keep them from backing off on the spring shackle thread.
Thanks for the sanity check...
