Looking for 4 Closet Door Rollers that match old Grant Rocket Roller

A quick learner from Greensboro, NC says:
Roller is 3/4" diameter with offset of 7/8" inch when measured from the inside of the offset; 1" when measured from outside of the offset.

I've tried to upload

Need replacement ASAP as I'm trying to sell my house. Will pay for expedited delivery/service.

Tried to upload photos but kept "Connection Lost" error messages. Happy to try to send another way.

Bob from SWISCO responded:

 Your roller has been discontinued for many years. The closest we have is our 23-003 , with a 3/4" off set and a 3/4" wheel. Please review. If that fails, we also can also recommend a new complete sliding door track kit like our 23-500 or other-sized varieties I have listed on this page.
