Zega top box

[spain]

Would like to get a zega top box on the @.Not sure if i need to buy a new rear rack to fit it to.Can't see any for sale on the touratech site.Does the top box fit straight onto the original?I've got an RD07 2002
Also would like a padded back rest for it.Does anyone know where i can pick one up.Thanks

OK...just found it.75 quid...thats 265 with the box....not cheap....Happy with the panniers tho,nice quality so just might go for it.
Would still like to get my hands on a padded back rest too...so if anyone knows of where to get them itwould be appreciated.Thanks in advance.
