Judging by the trim and the emblems on the rear 1/4 panels (which are kinda hard to read) it is a Delta 88. Delta Customs had a brushed aluminum strip down the side, Delta Custom emblems on the front fenders, and parking lights between the headlights instead of down in the bumper. Delmont 88s had Delmont 88 emblems on the front fenders and parking lights in the bumper like Deltas and 98s.

Pillarless coupes such as yours and pillarless sedans were called Holidays. The pillared sedan was called a Town Sedan.

The 2bbl 425s came in 300 and 310hp versions. I think they were called Super Rockets. I don't have all my literature in front of me. The 4bbl 425s came in 365 and 375hp versions, the 375 being the Starfire engine which came standard with dual exhaust. The only way to get dual exhaust on a 425 was to get the Starfire motor. I guess what I'm saying is that factory dual exhaust wasn't available on the 2bbl motors. If you've got duals, someone added them.
