91 Celica GT Convertible Speakers

I just bought a 91 Celica GT Convertible from a local dealer. When i looked at the speakers almost all but the ones in the dash were blown. I replaced the back ones which were 4" and it was quite a hassle getting them out. Could you tell me what size all the other speakers are before i get to take apart the dash and doors to replace them. If you could thatd be great.
