Found the exact part at Lowes after searching online. It would have been very helpful if they said it could be found elsewhere.

I had purchased a trimmer a couple of years ago. it wasn't used much, just on grass occasionally.
The orange cap/cover/circle over the line spool broke apart from the part that locks into the trimmer. Sears said the part is discontinued and that is that.
I am very frustrated I spent any money at Sears. Our family has purchased from sears for at least 4 generations.
User's recommendation: choose another company.
