If there is any doubt, replace with new 2% resistors, this will remove any chance of them changing value as the get hot/cold, even if they seem “OK” you can't account for how they will behave with temperature, pay vary close attention to R171/R172, these should be a matched pair, the higher the tolerance, the better, a matched pair will get you a more stable lock.

I do remember those 2 resistors and they were almost the same very little difference between them. What’s really odd is that the color seems to sync at random hot or cold now.
