Help wanted on replacing T40 AC power jack

I am wanting to replace the wobbly AC power connector in a T40 Thinkpad. I
already have the replacement connector which is a very straightforward
affair...a small cube with a Molex plug and a single screw hole for bolting
it down. I have studied the IBM MAINTENANCE PDF from the IBM website and
they make no reference to procedures for getting into the area where the AC
plug receptacle is located. Does anyone know what OTHER component FRU I
could check the procedure on that would get me into the same area that the
connector is located? Thanks.
