I want some white insert decals to put on the sides of my 88GT. I found some on Ebay for 5 bucks a set, now i only need 2 because i have a cobra rear bumper. The auction says its for 87 - 93 Mustangs, and the picture shown is on the rear bumper. My question is, is the rear insert the same size as the side skirts?? I bid on a quantity of 2 and i dont want to get stuck with 2 sets of decals that only fit a stock GT bumper.. Thanks
