Hey Mistryn,
A family member's work colleague has agreed to bring the speakers / harness over for me and is already maxed out on luggage sadly. He's coming for work purposes for 2 days and with an overhead bag so I'm already feeling guilty for my stuff taking up pretty much a lot of room so wouldn't wanna take the mickey.
Sorry I couldn't be of help otherwise I'd certainly have helped out. As I understand technic charges a very competitive rate for shipping to the UK and I have bought the harness from him before shipped here for my old car and it was delivered within 2 weeks, poifekkk!
Oh thanks for the part numbers buddy
