Unfortunately the gauges are M$ licensed, so no its illegal to distribute them, however its quite easy to substitute gauges from standard into panels, or alternatively look in the panel downloads for other panels you might prefer.
Aliasing gauges is quite simple in the aircrafts panel folder is a file called panel.cfg. If you go into that then all you have to do is change the name of the gauge you want there into one you have, don't alter the co-ordinates! And next time you fire up FS2k2 you should have the gauge there
