I know the 89+ front bumper lip (or spoiler) won't bolt up to the the pre89 bumper, is this just because of of the bolt hole locations? Or does the 89+ lip not correctly follow the bottom of the pre89 bumper. I ask because i'm finishing up my front end on the supra i'm restoring and i'm only lacking a lip. I know a junkyard around here has an 89 with a lip, and that's the ONLY lip i've been able to find, I haven't found ANYTHING else and it is angering me. lol. Thanks!
