OK, you have to post us a picture...
My 68 was SS cloned by the previous owner. Until I go to have it repainted, I'm driving it as is. Then, I'm going back to original. After all, isn't that what we are all about? We love the Camaro --the original Camaro.
As to the black vinyl top, the previous owner added it to my buttewrnut yellow car. I'll have to admit... it looks good. I've seen several posts on other sites that claim a butternut yellow car is "incomplete" without that vinyl top. But then, in both our cases, it would not be original. You might want to look at my poll:

Let us know what you decide!
