Dorwal broken latch from 1960s needs replacing.

A handy person from Alexandria says:
1960's latch is broken on our DorWal slider door (images show broken latch separate from door; door handle still shifts perfectly up and down using turn knob). Is there a replacement latch available or alternatively is it possible to replace the entire handle set but still use the existing sliding glass door?

We will also need new rollers for the existing door and screen. We can find out the diameter of the existing rollers.

Do you only need the keeper? If so, then I suggest our 89-014. You just have to cut down the pointed safety device. For the patio glass door rollers, it could be our 81-004, but this is just an educated guess. DorWal used this back in the 60's but there's no guarantee it's what you have now. The only way to confirm is to remove your rollers and compare them to our pictures and measurements.
