For my 92 Ty, I used Boston 746's in the front, which required minor modification of the grates (clipped the flanges from the posts on each corner) and then some Boston RM9's for the rear, which required some minor mods (clipped the waffle-like grids from the rear of the 6x9 covers just in the center to clear the tweeter, as well as the flanges on the posts.) and everything dropped right in. They sound good as well, although I am running an Infinity powered sub to make up for the lack of bass.
