We have the best in the world that keep coming back for years after their project has long been finished. The man with the 70 GMC that has the high dollar chassis and scruffy body drove his Mercedes convertible with the disappearing steel top to the shop and I told him I'd like to try this on an old car someday when I found one in the salvage yard so I could take it apart and examine it. He asked if I could put one back together after I took it apart and I said yes. He said he'd leave his and pick it up next weekend and in the mean time have at it. I'd bet all the levers, pivots, etc., have to be EXACT to position the opening and closing points repeatably. As you can see by the tools under the top the circus has already began.
My son took apart my really good, expensive, binoculars, when he was just a toddler. Found them scattered all over the kitchen table. To this day, after several attempts at trying to re-assemble them, I have wonderful magnification, AND, double vision. Steve.
The car is a high mileage car and the leather inside has many cracks but the offer was much appreciated, however, after checking it out it is WAY too complex for a street rod; as least the Mercedes version is. My nephew has a toy car with a disappearing top that I am going to buy one like it so I can cut into it and check it out. It's manually operated and MUST be simpler that the Mercedes.
