This off of a 2002 43' Mainship pilothouse side sliding door, this is the top roller set . I'm unable to match these anywhere .The lower rollers appear to be model 81-090 units. Any help would be appreciated .

The nylon roller looks like part of our 84-050N roller assembly. Think you can replace the whole thing?
