wanted for 900sd
 

hi looking for a complete gearbox or gearbox parts to fit a 1977 900 darmah or any idea where i might find one

Try either Road and Race in Australia or Bevel Heaven in San Franciso!

Or ask Pietro at Motori di Marino
http://www.dimarino.co.uk/

Or Nigel Lacey
http://www.laceyducati.com/ducati-parts/

Generally, there are only 4 bevel specialists in the uk:
Moto Marianna = Brian Silver (Berks)
Brancato Engineering = Tony Brancato (Oxon)
Ducati Technical Services = Paul Klatiewicz (Yorks)
Lacey Engineering = Nigel Lacey (Dorset).
All four are highly respected, none of them are cheap and they normally have pretty full order books.
Motori di Marino = Pietro di Marino (West Sussex) is a Guzzi man first but has loads of history and experience with Bevel Ducatis too.

Bevel gearbox
 

I can recommend VeeTwo stuff and fortunately it appears that Brook Henry has now bought the company back from the people he made the mistake of selling it to. It looks like he's manufacturing again -see www.veetwo.com.au. He's also on EBay - brookhenryducati - where he's got one or two gearbox items listed. Won't be cheap given the strength of the Oz dollar but might be your best option for individual parts.

many thanks for all the help guys
