They are only worth what people are willing to pay for them. Some people may be that nuts to spend $200 for a perfect one but most people wont spend more than $100 for a good one, and usually less. There is more than 200 because the 85's had them as well, and no telling how many 84/85 T-Types that were supposed to recieve the red dot, made it out of the factory with the turbo 6 logo. In fact its a wierd part and one that not many people are looking for, so I bet if you could get the part# on it and call up GM you could find a NOS one floating around in a warehouse somewhere.
