Will the header panel from a 1975 olds custom cruiser wagon, fit in a1975 Delta 88?

 

It will bolt up but the Delta grilles will not fit. The 1975 Custom Cruiser used the header panel from the Ninety Eight. Note the difference in the openings for the grilles in the header panel photos. The D88 grilles are rounded at the top corners. The Custom Cruiser/Ninety Eight grilles are squared off at the top corners. Also note that the center tooth is wider on the D88 header.
