I'm trying to do a 5 lug conversion on my 90 Lx hatch, I got 2 front rotors and 2 rear drums so all I need is the axles. The only problem is that I don't know what car they came from originally since I bought them from craigslist. I want to put FR500's, 18x10 in rear and 18x9 in front. Will they fit or will the back spacing not let them?? I'm on stock suspension but want to lower it on Eibach springs.
