from somewhere in my build thread... these are for my 1997 SV420, hope it helps somewhat?
new rear brake shoes fitted today + drums had a quick skim, the shoes were VERY thin & have worn more in the middle of the material than the leading/trailing edge.... is this normal wear?? they haven't been touched since i've had the vitara & i wouldn't be surprised if they not the original shoes.

RHS front shoe

RHS back shoe

they look to have the same wear pattern on both side so i assume it's normal.
i was supplied with N1735 shoes which weren't quite right some of the holes didn't line up & the location of the adjuster wasn't right, took photo's of the original brake shoes & went back to Power Brakes & the right ones which are N1758
