well, take say FC Metz (crap french team), go to thjeir kit in kitraptor, select home kit and export (save it), then the same for away and possibly keeper. then, have home kit selected and load the mansfield home kit, and select import kit - do the same with away and keeper and they're swapped
then go to mansfield and do the same thing with the metz home and away kits
if ur playing on tcm, open the editor, and go to mansfield - make sure the bar with the default kit options says FC Metz and u shud have the mansfield home, away and keeper kit. then, make the metzx kit say mansfield and they'll have their normal home and away kit without the keeper's one
if its fifa im not too sure wot to do after using kitraptor
and other kits you finished as well otherwise it will be a whole shipload of zipfiles
