Seat Runners

Have any of you fine chaps on here got a spare pair of runners / Adjuster for a Drivers seat you would like to sell,  mine has started to spilt out its ball bearings. it still locks in position but rocks about a bit.  I'm in no rush to get one but I plan to take my drivers seat out over the winter and fit the covers I have had for years now.

Happy to pay for postage as well as beer tokens
