ASM gerabox seal... Help!

[WheelyBigBox]

I'm having a rotten time... my asm motor went for rebuild.. they sent back a worse one, then they eventually sent mine back 2 weeks later, got it rebuilt (bloody pain with the silicone seals having enlarged themselves)... got it fitted...

Pipe has come off the clutch actuator. It plugs into a frankly awful bit of rubber that my ford parts dealers can't help with. IT's completely knackered - deteriorated all over with cracks etc. Pics below.. please help! I can't find one andit's an odd shape...

The rubber seal is clearly knackered but on inspection the inner part seemed ok. What i've done is stick the pipe into it while it's unfitted. Then i refitted it to the gearbox without the pipe in it. Then I attempted to re-fit it - twisting it back and forth as pushing - it went in a lot better thanks to being opened up while it was out of the gearbox but was still a pain. Eventually did it though and pipe is back in.
