Those are base model wheels that came on some years... not sure what all years but I know they could come on an 88 (I've seen them on a few). Sexy wheels
lol. Anywho, the new ones look very nice and the car is all the same color now... and it looks very nice! Congrats on the fresh paint/wheels combo! Looks very bueno! By the way, since that's a hardtop those wheels definately may have come on your car. If it doesn't have power options there is even a better chance. They came on a lot of base option cars that didn't get sports seats and all that jazz... but I've seen them on some t-top cars as well, so they may have just been the cheaper/cheapest factory wheel option.
