Let’s call them window sliders

These were out of stock for almost a year because the only company that made them closed up during Covid. I will warn you of 2 things (just installed them in my 70 Dart). To install them you have to take the whole door window/vent window assembly out of the car. When you install these they will be really hard to roll up and down - you have to pull up and down on the glass to get them to work - after several days of rolling them up and down several times a day they are loosening up and I think they will eventually work fine. Don't put the door panels on until they work right for you because if you roll them all the way down and they don't want to come up, you have to get your hand under the glass to assist them up. I adjusted my down stops so that the window wouldn't roll all the way down, until they work the way they should. By the way be careful when you take what's left of the old seals out because you have to trim the new material to match the old ones, both for length and a notch at the top to clear that rubber seal at the top of the channel. I posted pics of this replacement a couple weeks ago, but now I can't find them. If you need pics PM me.
Would you mind posting the pictures here.
