Certainteed slider lock replacement

A home owner from Fountain Valley CA says:

Hi,
The locking mechanism on this slider is failing. Can I replace the lock portion only or does it come with the complete handle? And, do you have the part?
I saw an earlier post from 2014 on your site. The customer said it was a Certainteed Somerton II Glider, and it looks exactly like mine.
Thank you,
Scott

If all you need is the mortise lock, see our 82-239. I believe this could be a match for your old hardware, I would just confirm our measurements all line up with yours!
