one went on here for £120 posted, i think it was Chris cocker selling it,
you would be better off splitting it and selling it as spares as there are allot of c4.2's still out there with drivers needing spares,
that's what i did with my C4.1 and made an extra £40 as they were going for only £90 posted
a bit more hassle but worth it in the end,
work it out what you think its worth in spares you will be suprissed
p.s. i will give you a tenner for your rear shock tower
