gear problems in 348 spider...

Hey all... completely new to this site... i hail from australia.

I have a beautiful 348 spider... that baby is my pride and joy... i was making a change from 2nd to third the other nite and then there was nothing... the middle gate which is 2nd & 3rd is completely free... there is no resistance in moving the gear stick from either gear. all other gears and reverse are clean. Im assuming it is something like a pin or something attaching the selector shaft within the gear box (i checked all linkages etc and the gear stick is connected all the way into the gear box...)

so thats my current predicament. now i need to fix it. there is no ferrari dealer here... closest one is 1600 km away (1000miles)... and they dont like giving u anything! so if anyone knows a link or can somehow send me a file that has the expanded workshop diagram of the gearbox of a 348 spider... that would be awesome... otherwise im a bit reluctant to let me mechanic open it up!!!

thanks heaps...
