Guys, this thread couldn't have come at a better time... I just looked at crutchfield.com myself, and the 6.5 fronts and 6x9 rears will fit, this is good not only for you folks but me too-I just got a nice package from my aunt who is not using them consisting of a good Pioneer deck and those speakers and I can use them now!
Based on what I read in one of the other threads on this subject... this guy
is my friend lol
1) the rear speakers are quite a bitch... just to get to

2) to get the 6x9's to fit in back, you might need to drill new holes and use foam weatherstrip to get them to fit flush against the deck
hope this helped
Steve
