The shields on the front knuckle, what the heck are they held with? Seeing the "bolt" head was hollow, I thought it was a Torx bolt (the whole set-up is very grimmy, so I couldn't really see). It's obviously not a Torx, but the "outside" of the bolt is round.
I thinks it a rivet. I just tried to remove mine to paint it and saw the same thing. I just used cardboard and paper towels to "mask off" what I didn't want sprayed. I know the back ones can be removed with 3 bolts.
Yep, they're rivets. You can drill them outr or use a cold chisel and hammer them out (which is how I took mine off). But if all you're doing is swapping what you listed, you'll have plenty of room without having to remove them.
