I think the correct terms are:"sedan"-with window frames and "hardtop"-without window frames.That's how the Hollander's interchange book distinquishes between the two styles.I think the term "hardtop" was first used around 1955 when GM began building 4-door cars with no window frames.
on camaros the vent windows were standard till 67, then in 68 they were removed permanently. I didn't think that it was really and option on the cars. I thought that it was the same for chevelles. maybe not.
