Gearbox / idler gear casing bits needed

Hi all,

1. if anyones got a complete gearbox they want to sell, doesn't matter if it crunches as i can mend that as long as it is complete.(later type rod change)

2. if no gearbox, i need to find a diff casing / the 2 plates that house the driveshaft seals that bolt to the side of the gearbox

3. i also need the casing that holds the idler bearings/gears (also housing the starter motor)

Thanks
Dan
