they are not made to lift, they are made to slide across ice. cause once you drill through the pucks and then throw a bed and cab on top of them, big no no. you don't just slap them in there and call it good.
just order a PA body lift and cut it down to 2 inches, it has been done. why just the front bumper brackets, what about the rear. Yes you may run into a problem if you only use 2 inches of the 3 inches, but i don't know and if you have a manual you will need the shifter extension.
I don't know of any where you can put just the body lift spacers. I'd just suck it up and spend the 150 and order the PA BL. The 03 front end has nothing to do with what BL you will order.
