Take it to the Gallery. They are Warwick Service people and they will do a cracking job.
There is no mount on the JAN, just carefully remove the old JAN with a Stanley knife blade as a lever, and sand off any glue residue, then a couple of small drops of superglue on the new one and it should fit perfectly. I have done this a couple of times. There's a guide on the warwick site somewhere on how to fit a new JAN.

Thanks Nigel, you are a top fella. Will give that a go this week.
Thanks to everyone else for the help.
