trailblazer Ext Fender Flares

I'm looking for OEM style Fender flares for a 2003 Trailblazer EXT
anyone have any information on where a person could find some
or who to contact about these, the normal trailblazer flare are
two piece rear flares due to the door going into the wheel well
the EXT door does not go into the wheel wel at all.

Thanks
