Window regulators, sash and rollers

[Pargolf]

Hey guys,

My regulators are rusted and frozen, so I ordered new ones. Since I found one of the sashes in the bottom of the door, I decided to buy two new ones, so I have regulators and sashes hopefully on the way to me now. My body shop guy was telling me there are rollers I need that go with the sashes, but my service manual makes no reference to it and I can't see that they do go on there. Any one know anything more? Appreciate the help all, the site has really helped me a lot and I've only had the truck a couple of weeks!
