Rear Hub For 136 HP Disco 2

I need a replacement rear hub for my son's 2002 Disco 2 136 HP. Ebay says that part number TAY100050 is not suitable. They only seem to have hubs for 139 HP. Is there really any difference, can I fit a rear hub for a 139 HP? Any advice PLEASE.

The main suppliers all seem to agree that TAY100050 fits all D2's

They're the same for all D2s

And You can put a front hub to rear, they are the same except front has longer ABS cable.

EDIT:
Correction, Rears You can put to front, not the other way round.

Rears have an o ring as well dont they...

Yes, they do and front ones dont have the slot for the o-ring so it's possible to fit a rear one to the front but not the other way around

Thank You for correcting. I'll try to remeber this the correct way

Thank you, I thought that might be the case. Don't see what difference 3 BHP would make. Ebay seems to be wrong.

The BHP is completely irrelevant for the hubs... mine has 30% more BHP cos it's remapped
