in the front bumper diagram...the insert is item number 51111834874....and sells for $76.82 on the OEM website...
notice...in the forum sections for e21...there is a lot of talk about re-working the sheet metal for rear bumpers...apparently some holes require filling...and places where the federalized bumper fits there are spaces of some sort where the rubber fits...check fitment of rears before sending to body shop...
