I was reading the options list and wounder
what are the option power roof?
it cant be the electrical convertible top becuse it is named convertble top power.

The optional power roof must refer to the power convertible top. Chevy sold convertibles with a manual top. I think the manual top is operated by kneeling on the back seat, grabbing the bow on folding top and pulling it up. Chevy did not offer a sun roof back then (at least that I know about).

I agree with Texidon,

Except my manual top was balanced enough to lift from one side while standing outside...
