Oh fun - now time to pull rivets!
I tried torch, hammer & punch, drilling, etc.
What I found worked best is to use an angle grinder or, where necessary, a die grinder & burr to either make an "X" in the head of each rivet, grind it flush, or cut the head off it with a cutting wheel.
From there, air hammer + punch bit. More air pressure = better. You'd be surprised how much more kick it has at 150 psi vs 90 psi. If you don't have an air hammer, it's worth buying one just for this.

I'll be super excited to see the Industrial Chassis kit install! Thanks for sharing progress!
