classic team jersey

hi guys
i have a question.

i want to make classic team's jersey normal jersey,not short jersey.
how can I this?
I rename normal nba team(ex:La lakers: ua005.iff) jersey number to classic team(ex:96 supersonics : ua562.iff) jersey number.
but it doesn't work.
there is no change. it's short jersey in the game.
not normal jersey.

sorry, my poor english.

its because of the roster file, which controls what model the uniform uses.
