There is ABP in Crewe and TDI North in Warrington, there are not 350z specialists by any means but i think they can get hold of quite a few bits. Other than that i think we'll just have to make a day trip out of it!!
If you do find anywhere else, let me know bud
I have been intouch with TDI North, they can get bits for the 350.I also asked them if they would would fit bits that i bought else where,they told me that they would.
Seem very helpful.
