Hey, I too own an 88 Z24, and you might as well give up! There is one idea that a few guys threw at me though, buying a body kit for a 91-94 Z24 is supposed to fit. I am sure there would have to be some kind of modification done though.
Hope this helps, and if you know wehre I can get aftermarket parts or even stock replacement, please email me and let me know.
