Its pretty easy to do Ed, you just have to be careful when bending the ear back as not to break the paint, i would heat up with a hair dryer first to be sure.
if you are planning to take it to the ring soon then the liner mod aint going to help you round there. If you are getting rubbing under normal conditions, then a lap round there ( especially the carousel ) will find you out.

Good question about moving the lining, Mr Edd
cant believe VWR havn't already done this on yours Robin, i am pretty sure if you look under there it will already have been done.
