I actually had one of those a Super 88 Convertible and in that same off white color. It was my first car and what a tank it was.
I still recall getting it registered in N.Y and being registration was by weight I recall it tipping the scales at 4262 lbs.

If anyone is interested, somewhere at my brothers house I still have a set of cylinder heads, valve covers a 3 deuce manifold and carbs.
