88 is the pleated pattern design, he must be using an 84'-85' Fiero seat if he has speakers unless he is adding them. So Valley, did you go with a full pleat on the bottom of the 88' like mine or the standard half pleat? All vinyl or leather vinyl? Regular grains or the mixed stock Mustang type? I assume you tore apart the seats already? Have you decided on your seat track set up yet? Details man!!!!!!
