Rega P3-24 modification...rca jacks and earth

Long story built in interconnects are shot. rather than just replace i would like to just mount rca jacks on it and would also like a dedicated earth connection.
Whats the best mod kit out there for my table to do this? or just buy the parts and rig it?
I would call The Cable Company. They have just about anything you can think of. They will also give you really good advice. Also, you probably don't need to use a ground. Not having a ground allows you to use just about any IC out there. I don't know of anyone still using a ground. (I'm sure that some people still use them, but its not that common.)
