GM rear tail panel?

[67_C-30]

I had a black '73 Laguna S-3 with 454, TH400 about 10 years ago. It waas like the one pictured below, but had a white belt line stripe and a white interior with swivel bucket seats. Its one of the many cars that I wish I had kept. The '73 had round taillights and I think your tail panel you had is from '74 or '75. '76 had long tail lights more like regular Malibu's IIRC.
