Go for it but go for it with your eyes open. The clutch being cable operated is only a minor difference to production 260s, the prototypes differ electronically as well (ECUs etc) and not sure how much help a T4 (or TOAF) would be. That's what put me off.
I had photos Paul took of 003 residing in the Bristol garage but not sure where they are
