88-89 USDM bumpers have the indention where people often pin stripe it. The 88-89 front bumper lenses are different than the 90-91 ones too and they have 2 different stock front lips .

A follow up question: What year JDM bumpers and moldings have the indention for a pin stripe? I've seen different years listen when they're for sale, but i've seen the same years with no indention...
