Box opened to check contents and photograph but brand new never fitted.
Bought to fit to a previous car I owned which didn't have a slippy diff. Current car already has one in so surplus to requirements.
After £650 ideally collected (Rugby, CV21) but will post at cost.
These are approx £800 from Quaife.
