Inatalling door handle 40-150

A quick learner from Pittsboro NC says:
The spring in the door handled had broken and I have ordered and received the replacement top part of my storm door (40-150) from a photograph on your website that a customer had the same problem. I need assistance in helping to install this part. Can you assist me ASAP?

Good Morning,

First, check to see if you need to remove the inside sector to match the hole on your existing spindle. I've done this myself and had some trouble removing the spindle from the old existing lock. Some of the existing handles may require you to completely take it apart in order to remove the spindle. As I said earlier, I have done this, however it is not a simple task.
