As title....I've found a bloke who has just taken delivery of a crate of second hand Ford Type 9 gearboxes. He's a gearbox reconditioner and is going to strip each one and rebuild with new bearings, seals and whatever else they need.
Because of the work involved (and it's how he earns a crust) he's not giving them away but as these are getting more difficult to find, I though I'd pass on the info. He can also rebuild your own gearbox.
Anyhoo, the bloke is Rick and he's here: Northern Grearboxes

Mention me (as the bloke with the 4x4 ambulance) and I may get a free coffee when go to collect my gearbox.....
