I've a few bits that need a new home after an early spring clean, so if they'd be of any use to you then let me know.
First of are some 5mm universal shim spacers that I have, nothing special but if you want them they are yours for free, just pay the postage. Fyi as with any spacers you may need longer studs fitted dependent on your wheel design and offsets.
Next is a good old OEM Bluetooth module first me 80 quid way back then but happy to let it go for 20. Be warned you need a pretty old phone for it to be of any real use, modern phones just won't work on it too well.
Thirdly I have some brand new Whiteline ARB bushes, front and rear. I didn't need them when I replaced mine ARBs as I had some nice Superpros to go on instead. £45 for front and rear together.
