Mod top/No mod top?
I'd put the top on... Mod tops are cool. You could always buy the top, lay it on the car and see what you think. If you you don't like it, put it back in the box until you deside to do a by the numbers resto.
My '68 is red w/ a red strip and maroon interior.... I don't care for red cars ( no offense to anyone that does). My car is going back all stock when I'm done with it though. The factory red w/ red kind of "ghost" stripe will look cool though.
