Broken Sewer Connection Stubs

[AZ_JOE]

On a cold morning, two of the four sewer line retaining stubs broke when detaching the cap. See pic below. Does anyone know of a manufacturer of stubs retainable from the inside? I am thinking stubs like these would have the same dimensions as the broken ones, be tapped inside and be secured by a screw after drilling pass-through holes into the connection for the screws. My preference is to avoid having to cut and glue a new sewer line connection. Again, your insight is appreciated.

You might be better off going with one of these from Amazon:
$6.70 is pretty inexpensive, and a lot less messing around
Valterra T1029-2 Termination Adapter

Thanks Albert. I ordered your recommended termination adapter.
