Front Drum Glides

[SIZE=3]After reading the posts and dismantling my GE clothes dryer I’m confused on how many “slides” I need. The only ones I discovered were 1 White and 1 Green also the diagram shows only 2 but on the posts I read that there are 2 white and 2 green. Can you please clarify how many and location.[/SIZE]

Here is the parts diagram for your model.

I only see one of each too. The other post you read are they the same model dryer?
