Oh no, not the Griffith Sunchaser. There were thousands of those. I'm sure one would have more luck finding a top for that.
This is an early picture of my car, from the add when I bought it:
A more recent photo:
Changes include lowering the rear slightly, 1986 Celica GT seats, 1984 Celica GTS wheels(1.5 inches wider), 1980 Supra rear axle and sway bar, and a grant GT steering wheel.
I had 5 other 76-77 celica liftbacks through the years. Two drivers and three parts cars. One was wrecked and the others eventually rusted away.
Here's my old 77 I had up until a few years ago:
It was lowered considerably, had the rear fenders cut and tubbed out, also had a Supra axle with rear disk brakes, 14x7 inch Supra/GTS wheels, had a w58 transmission, twin weber dcoe side draft carbs, headers, and extra firm anti roll (sway) bars. As one can see the bumpers were removed for lightness and I blacked out all the chrome.
