I purchased a top from Al Knock. But I have not installed it yet. Mine is just the basic white vinyl top with teh plastic window. Also, I purchased his install dvd which I have watched once. But I believe it will be very useful. The top looks fine in the box but cant tell you any more then that for now.

Does anyone know how to tell the date codes on C4 convertible tops to tell if it a original top?

You've asked that previously and never supplied a snap-shot of the tag displaying the information!

Remember?

Yes, here is a photo of the OEM Ultralite top from a 1989 Corvette roadster. The date code is April 1989.

What about HAARTZ?

It seems like they make good tops.

Im also going to convert mine to glass rear window (even though I hate to add weight) so that I can tint the windows. Which I think looks on black cars.

HAARTZ tops are great and look cool, but I think they only come in black.

I'm pretty suire that ALL white tops on early C4 roadsters were vinyl and all black tops were the fuzzy HAARTZ tops.
