Impossible to say with any degree of certainty. You could possibly determine the number done by Sheehan(European Auto Sales, Costa Mesa) and Straman. As far as the rest, using the ubiquitous "Scaglietti clip" who knows?
Does Straman still exist? At their early 80's rate the Daytona Coupé would be rarer by now than a genuine or fake Spyder. Thankfully the market seems to have recognized the value of originality, with both 365 and 275 coupés normally fetching higher prices than open fakes. In any case, there are far more fake 275 than genuine NART Spyders.
While we're talking about open 275's, according to an RM (I think) article only the first 4 NARTS were built as Spyders from the ground up, the remaining 6 started life as Berlinettas and were soon decapitated by the factory. True?
I have 19 so far: 07061, 07211, 07603, 08039, 08391, 09603, 09635, 09851, 09987, 10131, 10223 10351, 10473, 10527, 10669, 10743, 10875, 10917, 10969
Not quite "100's". To quote Michael Sheehan: While many attempted conversions, four shops did most of them: Autokraft in England did about 10 cars; Auto Sport (a.k.a. Bacchelli) in Modena, Italy, converted about 25; my shop, Michael Sheehans European Auto Restoration, in Costa Mesa, CA, did about 28 conversions; and the Richard Straman Company, also in Costa Mesa, CA (on the same street and only a few hundred feet from my front door), converted about 35 Daytonas. Throw in a dozen or so cars done by long forgotten shops and you get a total of just over 100 cut coupes.
+ 10621 which in 2003 was in England, silver with red. Query on 10131.....is that a 4 cam number, in the RAAB book its a 330?
There were also some 2 cam versions that were converted. About 6 or 7 years ago I was seriously considering a "cut" blue 2 cam that Sheehan was marketing. Just like many converted Daytonas the price of the cut 275 was about the same as the coupe......at the time $400k. The car ended up in England I believe. I noticed in the latest FML that there are 3 converted Daytonas advertised......at about the same price of the coupe. I have not see any converted 275s marketed lately. BTW I still think the NART Spyder is one of the most beautiful shapes on the face of the planet.
I am sure you have been following the saga of this effort. Once a subforum is established data on these cars will be an important part of the data base to be created. They will come under a "rebody,replica" category and help to bring these cars out of the shaddows. Comments and opinions are always appreciated. tongascrew

Wasn't the question. "how many GTB's were converted to NART spyders". Were 19 conveted for or by Chinetti for the "N.A.R.T."? I'm not educated enough to know. I was told it was 6 cars by Chinetti with two being in all aluminum coach work. I've seen one alloy bodied car,...it is stunning. ~Ciao and best
Here’s a pic of a cut 275 by Straman. I took the picture while visiting his shop with my father. Image Unavailable, Please Login
One tired red 4 cam was sold from Motorcar Gallery in Fort Lauderdale in 2002 or 2003 via Adrian Hamilton to a UK buyer who had it cut. Don't recall the chassis number but would recognize the photos.
