I agree they look like Olds....maybe '48/'49 98 or possibly '49/'50 series 76 ??.......do not think they are 88's Ray
The '49 Chevy lights are a little wider, and slightly shorter, and have a lens that follows the bezel contour.......very similar in appreance......a '50 Chev taillight has same bezel as '49 but should have a different lens.....lens at top 'sticks out' from bezel and slopes to meet the bezel at the bottom.....
