Mk3 Gearbox End Casing Gasket Leaking

[PhilC85]

I have an oil leak from the end casing gasket on the gearbox of my 1.6 Zetec Manual 61 plate MK3 focus, I'm struggling to find the part numbers or any info at all for the parts circled in the attached image. Is anyone able to help out please? I've scoured the Haynes manual with no results.

 

** Image is of Fiesta as cant find the correct diagram for the mk3 Focus.

 

Thanks

Thanks for that, am I correct in saying its parts 7L301, 7B343 & 7211 to complete the full seal as the rest of the gearbox is a solid unit? 

Thanks for the guidance

7l301is the gearbox casings. So you won't need that. Are you sure it's leaking from both gaskets? 

Gaskets are 7223 and 7b343

From what I can see its leaking from drive shaft seal and that also heres a few pics, I'm no mechanic like could do the job myself though so want to try work everything out that I need etc
