I posted that because you can call EBC, Hawk or Porterfield and tell them you have a 79-84 toyota 4x4 pickup with S12 stamping on the side. No custom made pads.. they all make pads for that application.
Only the 300zx pads are interchangeable with the vented brakes, not the non-vented from memory. If not.. just trim the 300zx pads.
