1982 Anderson patio door rollers

Andersen doors often use the 81-128 Andersen Roller or our 81-018, but I can't say for sure without seeing your old roller out of the door. Compare it to both to see which you might need. 

There's a few different possibilities for the weatherstripping. Can you remove a sample and show us its end profile? I know it's possibly brittle and hard to remove, but a cross-section view should help us identify any possible replacement. Many thanks.
