No... looks like I have to take the bezels off each end (screws are rusted solid to the clip nuts, naturally). There would be no way to reach the bolts that hold the grille mounting brackets to the fender with the entire grille assembled and the bumper and valance mounted.
I don't even remember how I removed it. Or it may have come off in pieces, possibly by the previous owner, and then reassembled to avoid losing pieces
I've been turning wrenches for over 40 years but tried to avoid body/paint/interior stuff. It's so time consuming, expensive, and doesn't make the car run any faster!
