Not sure how helpful these pics are at showing the bolt size compared to an AA battery but this is an M10 bolt from the supermoto caliper bracket to suspension tube mounting bracket:



So just to conclude the thread, if you're bolts and corresponding fork bracket mounting holes are M10 (2001-2004 SMs) then the bushings will not work.
You will need to get the enduro caliper drilled and tapped to accept M10x1.25 pitch bolts and space them with nuts that are 5mm wide.
