Just after replacing a damaged CV boot for the test and after refitting the driveshaft I noticed the next morning that it's after springing a leak

Ripped the whole thing apart again and don't ya know I'm after damaging the drive shaft seal Where would I locate one of these in a hurry?
Is there any other vehicle using the same seal, could I locate one locally?
The code on the side of the seal is 15z 35 56 16.5 AE
I need the van for the weekend
