All body parts in the B series from 1986 to 1993 are interchangeable, the body remained the same through all those years, just make sure it fits your truck's configuration (reg cab short box, reg cab long box, Cab Plus short box, 4x2 or 4x4). Although the box from a reg cab short box and a Cab Plus model are about the same size, THEY ARE NOT THE SAME, just take a look at the wheel well (a little forward in the Cab Plus box). Another difference is the tail gate, from 1986 to 1987 the Mazda logo was embeded into the metal while from 1988 to 1993 it was replaced by a sticker on the lower right side of the tail gate.
