Refrigerator Came With House - Had missing parts

The refrigerator that came with the purchase of my house had a missing retainer bar in bottom shelf of fridge and a duct-taped retainer bar in freezer. When parts came, all I had to do after removing the duct-tape, was slide up the broken end cap to pop it off then, snap the retainer bars into the end caps and slide them down into place. No tools necessary. Should have done this two years ago when I bought the house!
