Product review (5 stars): exact replacement if your fridge uses this exact part
This is an exact replacement for the original part.  Get the model number inside your fridge and find the parts list online (usually a PDF file) and verify that this is what you need- the part numbers will line up.

I expect most people are replacing this part because the plastic pivot nub for the deli drawer snapped off.  Perhaps this is a poor original design.  At any rate you'll need to figure out how to remove the old part yourself.  For this right side part, you won't need tools- it is all tab based.  The whole thing comes out together along with the crisper apparatus that runs along the back of the fridge.  Once you've gotten it out you will need to move those parts over to the new end cap.  You'll also need to reuse the metal drawer slide, which also comes out by depressing a tab.  I can't say exactly what particular bit of magic gets the old end cap out other than you have to understand that it comes out together with the crisper apparatus.  If it comes out separately it means you broke something.  I did unintentionally break one of the tabs on the old end cap during removal which actually seems to help get it out (and didn't matter since the part was going in the trash anyway.)  Good luck.
