Shouldn’t you be pointing your customer towards the massive safety recall. Given the tragic events of the last few days do you want to risk repairing one?
The only seal available is the very front seal, the spongy bits on the condensor itself are not available but something similar to those can be obtained from most major DIY chains.
See attached picture for the one seal you can get.
Cheers Jim the seal I’m looking for is the 2nd rubber one. I will be letting my customer know do you know exactly what they are doing with the m/cs to sort this. The motorbike is gone Jim
