Had a lot of reading to catch up on and kudos on getting this whole debacle sorted! Can't wait to see it posted here. I remember how heavy my one was and like you said, taking the hit for postage is something we are well used to here in Ireland
I had to have a read through the Radio World shop feedback on Ebay and they are not great. They must either be in trouble financially or have very inept workers there. I hope they get themselves sorted as I had no issues dealing with them a few months back and charged me a reasonable fee for shipping it to Ireland.
Spade connectors will come in handy and will make a tidy job of the speakers.
Btw, that colour for that Focus looks Olive Green to me. Unusual and I never seen one that colour. Definitely an option. Also, saw a Lime Green Focus RS today around Tullamore and it was a beaut!
