Gen 2 Tail On Gen I Regulator Mount

[Taribare]

I am going to drill and install new riv nuts on left side so I can keep my wires routed on Gen I side. I have the relocator bracket already. I will be using 6 mm Riv Nuts. My question is what material should I use on the riv nuts? Stainless, aluminum, or the zinc ones. I assume they are aluminum ones on the right hand side of sub frame on the Gen II. Thank You for any input

I just noticed the factory riv nuts have a tack weld on them, have to be steel ones.. so that's the route I will go..
