I installed a new soft top rear bow on my tracker, the paint and rubber on the old one was in poor condition.
Takes about 1 hour, keep the top up, unsnap the top from the bow, you may want to use a small screw driver w/thin blade,
push between the male/female snap or push open w/thumb (it takes a hard push). Always be careful with the fabric top. Remove the side mounting screws. Keep one end high and the other low, the bow will come out the front door.
I got the bow from suzuki, chevrolet has discontinued the bow, many of the tracker and vitara basic parts are the same.
