I meant to mention that about three or four months ago, I purchased new two centre boxes for my 2.6V6. When the package arrived (from Poland), I dutifully took the boxes to my mechanic friend to have them fitted, only to find (after the old system had been removed) that they had sent me two driver's sides!!. The mechanic was able to put the old passenger's side box on, so I could get home and make the necessary demand from the seller to send me a new passenger's side one. A few weeks' later it duly arrived and I had it fitted. The seller told me he would arrange collection of the surplus driver's side box. Needless to say, that despite text messages, I've heard nowt.
Today, I sent him a text, saying that unless i hear from him in the next few days, I shall dispose of the drivers' side box, as it is taking up too much room in my shed. The upshot of this is that I may well be giving away a centre box in the near future (collection only!).
