Hi there, Zafar.
Take a look at the list of Andersen parts that we've related for you on this page. Carefully review the specifications and see how they compare with yours.
If you have any questions just let us know!
Yes! Our return policy can be found here just in case.
For the 88-014 exterior pull handle, take a look at the 33-109B Andersen bolt. This screw fits the #10-32 thread count in the handle and is 2" long. I'm just not sure what the thickness of your door is. It might be best to take the original screws you remove from your door and take them to a hardware store in your area to have them match up the installation screws.
