the original slide rail for the meat drawer in the fridge broke

I took the original shelf out of the fridge with the brackets and the slide rail attached. The most difficult part was actually dismounting the slide rail from the bracket so I could replace it. I did this by leveraging the rail away from the bracket with a screwdriver so it could move freely and then banged it out. Once the old slide rail was off I just snapped in the new piece, screwed the wheel from the old rail onto the new one.
