I put PitBull spools on another bike -- hollow steel swingarm. No problems. Rivnuts squashed perfectly.
But now I am looking at my 900sp, which has an solid-bar aluminum swingarm. No place for the rivnut to squash. If I drill into it with a 25/64" bit, it will make a clean hole straight thru.
Has anyone put these onto a bike with a solid swingarm?
I looked on the Pit Bull website:

Net: Do not use riv nuts on a solid swingarm.
Allows spools to be added to hollow swingarms. Drilling required.
so the net is that I need to drill and tap a smaller hole in the swingarm, no riv nuts. I am thinking I might use helicoils or similar to have steel teeth instead of a steel screw into the aluminium. The mounting screws are 6mm.
