I just installed a new stereo system in my Trac including new speakers so I don't need the factory ones anymore. If anyone is interested just make me an offer and cover shipping!
There is no reason they shouldn't. The speakers should be a perfect fit and easy install. With the sub and amp, if you want it to look factory then you would need to find the housing and sub box that goes behind the back seat. If you don't care about the factory look than any 8" sub box will work.
