They don´t necessarily make a body kit for the LX itself, but they make stuff for the GT, which I think would fit the LX... www.nopionline.com see if you can get that bumper, rear fascia and maybe the sideskirts (if you own a two door LX).
The best front bumpers that will fit with a minor modes are from CRX or early 90s civics. Also side skirts will do as well. Late 92-95 Civics are wider.You´ll have to make a fenders flairs to cover the holes. Side skirts are no problem.
