Convert 760L to 760LD?

[Jim McGhee <jmcghee@cyberramp.net>]

Hi,
I have a ThinkPad 760L that I like very much, but I can't put an
internal CDROM in it because it is the 'slim' model.  I was wondering if
the only difference between the 760L and the 760LD is the height?
If so, could I get a 760LD bottom and swap it?  What else would I have
to swap?  I know IBM Direct will sell just the bottom.

BTW, I also have a TP701 that I need a port replicator for.  Anyone know
a good source or have an extra one?

Thanks,
Jim McGhee
