355 Shifter Assembly and Pedalbox needed for Late Model 355s

Good morning fellow Ferrarists, my friend in San Antonio has two 355s in his garage with the F1 setup, both car owners are looking to convert to 3 pedal cars. Obviously parts like these are difficult to come by, both cars are the late model Bosch ABS system and the earlier systems are not compatable. Any help in locating parts would be greatly appreciated and would get 2 more ferraris back on the road. Thank you very much in advance!
