I plan on changing the radius arm bracket along with the bushing. Any tips or suggestions when I attempt this.?

 

My angle grinder was too big to get to most of the rivets. I ended up using carbide burrs on my air die grinder.
Wear eye protection, replace with grade8 bolts.

 

I was able to drill the heads of the rivets and used an air chisel to pop the heads off and to drive out the rivets. +1 on the grade 8 bolts!
If your ordering in all the parts I would order a new heat shield for the passenger side - mine was pretty corroded (and I don't live in the rust belt)

I used a torch cut the rivets kinda risky but got it all done. Wasn't as bad as I thought it would be
