Thanks for the help, guys. I called Will Samples this morning, and he said the parchment top hasn't been made in years. He recommended GAHH. The GAHH website didn't show this color, and tops in other colors started at $625. I really can't drive the car much in this weather without a softtop being available, so I just decided to put a black top on. Black over red isn't so bad anyway, but I hate to loose the authenticity. The white top from Millers might be too light, so I decided to pass on it.
I ordered the top from PrestigeAutoTrim in England; this is the source of the top I put on my 230SL a couple of years ago. Yes, I did it myself. I think this one will go faster, but will still take most of a day.
