Trying to find replacement door handles for my patio doors

Hi, I bought a property that came with the larger sized handles in the picture above. They've never been right and keep falling out. I took them out and tried to fix them and in a moment of bad judgment stuck them together. They won't come apart and need replacing. They're done.

I ordered these from you https://www.swisco.com/Handle-Pair/pd/Replacement-Storm-Door-Handles_Locks/40-184
They're great and fit the bill except that the metal rod is too short. The measurement of the rod on that product page is exactly the distance when the two handles are connected in my original handles, so I figured it was worth a shot.

The handles I bought from you, I actually really like and would love to keep. Do you sell a rod that I could use to lengthen the handles? Or if not do you sell handles that have a longer distance between then which would work with my doors?

Thanks!
