That is amazing that’s that the original roof from the same car! They just needed a few bits to go with it:- New rear wings, new rear panel, new boot lid and frame, new rear glass, new rear quarter light glass and frame, new door glass, new door frames, new outer door mouldings, new fibreglass tub or re-install the rear bulkhead in fiberglass and the rear inner wings to the remaining tub, remove any extra strengthening that was added, new frame work to support the roof, new roof liner etc. etc. and put it all together accurately, which hopefully they did ! That would have been an expensive job to say the least, and it will always been know, that at one point it had been converted into a spyder, so the value will be less and it will be harder to sell, despite the company's great reputation that put it back together. Still it could get Ferrari classiche now !!!
