well im sorry to say, that without doing alot of customizing the mazda truck grille will not fit. it is a different body style than our explorer ranger navajo front end. the 93-97 mazda truck looks alot like our grille but the truck is based off the second generation ranger. i hit a deer with my navajo and i ended up replacing the grille reinforcement with a junkyard one from maine. ($45+ $45 shipping) i bought the marker light off ebay for $35 + $5 shipping. and the grille i bought off of parts.com for $190. the cheapest way to go, is to buy a ranger/explorer grille, the full headlight set with corners and turn signals and mounts. and just put that in. i like the mazda front end so i payed the higher price to fix it. you could check car-part.com also. it sucks to hear another navajo needs a grille because i know how hard its going to be to find it.
here is a link to mine when i did it... if its any help...
