Indash cd changer help

[me2you1]

Okay so I got my 99 Galant yesterday, and I'm looking for an in dash cd changer. All i can find is ones from the 2003 model of Galant. Now I'm wondering if the 2003 6 disc, will work in my 99, like dimensions etc.

A9002RCX01 <- thats the model number for the 2003

Any Help would be extremely great!

thanks, andy
