1997 speaker size

[Cadillac]

Ok, so Im looking for some new speakers, and yes, I did do a search first but couldnt find anything (maybe I searched te wrongwords but I did search). Anyways, I have a 1997 GT Vert, and one place tells me 5x7s and the other place says 6x8s. soo, which is it? and which are some good brands to go with?

6x8s all the way around unless you use smaller with adapters. dont be fooled, go with 6x8s.
