The rear bumper on this site is posted for both the 90-91 and the 92-93.

Other than the obvious exhaust issues, will this bolt on into a 91 Integra. I was asking because i SEARCHED and somebody had posted that the 92-93 WW rear bumpers will not fit 90-91 Integras, but if this is so, why is this bumper advertised for 90-91 integras as well? :shrug: Just wanted to make sure. TIA
