Not really mate, you have a threaded rod down the inside if you unscrew this from the cap will the alloy slider come off the end without undoing the allen bolt in the bottom. If so they are early 500 K0and some K1, but not UK models. Put up some pics and tell me how much, forks are always usefull and i do have several to build. Or mail me direct to blj@blj.org.uk
