Thanks m'lud,
my 25 year old wires are unsealed and would need tubes fitted. Life's, my local dealer, have hooked me up with a set of Avons and will arrange for them to be fitted next week when the chariot goes in for MOT. They have a local supplier who's very understanding and likes to keep Morgans as British as possible and is able to handle and balance centre locked wires properly.
Job done!
cheers all.
