Welllll,Only Alfa Romeo would take one car (2000), completely redesign it to look basically the same (2600) but have virtually no body parts in common and only a few mechanical parts in common...sorry. You can probably find a 2600 convertible top frame on eBay (check worldwide).
Well, that's where I draw the line. The windshield and its uprights and horizontals are definitely the same for the 102 and 106. Plus, it's the same part number for the door handles, 102....The "door handles" are 'basically' the same, except the bolt for the plunger that you push on with your thumb, to open the door, is about two inches longer on the 2600 so the doors are thicker as well. The fenders are all slightly different, the hood and trunk lids are different, the hard tops are different. I suspect the windshields are different but don't know for sure, the 2600's looks more vertical or upright.
Just an image from the net... just like the 2000.
The Volkswagen Beetle and/or Mercedes Ponton of the same period probably would also qualify.I still say, only Alfa Romeo would take one car (2000), completely redesign it to look basically the same (2600) but have virtually no body parts in common and only a few mechanical parts in common...
BTW, my eyes aren't resolving this picture. It appears there is a "pocket" for the stainless trim strip, and that the strip is well below the door opening.I had two doors from a 2000 roadster and I stored them for more than 30 years. A few years ago, I posted a notice on the Yahoo 2000/2600 forum (that was before everyone moved to this group) that I would give them to anyone who would pick them up in north Florida and that person could store them for the next 30 years. After begging for weeks, I threatened to throw them in the garbage dumpster and if someone did not contact me by a certain date, that is exactly what I would do! Well, a man in Miami called and said his cousin, who lives in Gainesville would call me and pick them up for him. Sure enough, he called and picked them up. I probably would not have thrown them away, but after moving from south Florida, I had almost no storage space and too many Alfa and Porsche parts.
The poor quality picture is my 2600 Spider door, showing the lower front corner. My car is an early one, #191207 and since I have never had a chance to inspect other 2600s, I assumed all of them had a rounded corner. The vent wings on the 2600 doors are actuated by a knob on the door under the vent wing. It is not opened by unlatching a lock and pushing it out like on lesser cars. The structure for that gearbox is not in the 2000 door. The structure, at the front of the door, for the roll-up side glass is missing, etc., etc. I know that any talented bodyman could build the 2000 door for use on the 2600. Hell, I could have done it myself, but it is not a simple matter. So now, someone in Miami can store them for 30 years and then HE can throw them away.
