Lister Knobbly Replica - I want to go hillclimbing

[Sauls]

Hi - Im new to Pistonheads and am after making contact with anyone that can help with advise on how i can get started in motorsport (possibly hillclimbing to start).
I live in Chelmsford, Essex and have just restored a Lister Jaguar Replica - JWB 976C. I want to start doing some motorsport in 2012 and though hillclimbing could be a good intro. My car has a long racing career - but I dont - although do have a national B race license. Has anyone out there got any good advise on what clubs to join etc. - or would be interested in helping.
Regards,
Saul
