Hello all. Have recently bout a 99 B4000 with extended cab. For my son. Someone along the way did away with the rear seats. What I was hoping someone could tell me was what year range in both the Mazda and the Ranger, could I use to search for some replacements. In other words, "the 99 B4000 rear seats were the same in Mazdas from 19nn to 20nn and in Rangers from 19nn to 20nn"...... Anyone know that info?....thanks in advance.....
