1970 Duster Passenger Quarter Install

Texas340 · Jun 23, 2022

Howdy. Getting ready to install the passenger quarter (from AMD) on my '70 duster. I was told taking the quarter glass rounded brace off would make it easier.

How would you reattach the brace once you get ready to weld in the quarter? Is there a better method of installing the quarter?

@Oldmanmopar can probably answer this better than anybody. He has fixed more Duster/Demon cars than most of us have seen!

Been making progress on the '70 Duster quarter. I am having a little bit on an issue with the top corner in the door jam.

The picture with the silver mark shows the gap between the new quarter and the door. The body lines are lining up near perfect, with just a larger gap at the top of the jam and a narrower gap toward the bottom. My thought is this is part of the AMD panels that are known to have gap issues right here. What do you guys think?

From what I’ve seen people do. They are pie cutting the top and adding a piece of their old quarter panel to get that gap closer

Yeah I have seen that, too. I was thinking I could adjust the door some to close the top gap and open up the gap towards the bottom. I am on the fence about this though because my body lines match up dang near perfect.

Reminder to self.....do not destroy or throw away old quarter before new quarter is installed.

I hope Steve will chime in here, but yes; the stamping slips, or the die is just a little off. I had to do that to my Demon, and I've seen a few build threads with the same issue.

Thank you guys for the info on this. I made the pie cut on the quarter corner and was able to get a door gap im happy with.

My next question would be the quarter window. I had to split the top of the quarter right below the quarter glass to close the gap between the quarter glass frame and the panel. I got it pretty close I think...I wanted to get some opinions on this before I welded everything in. I included a picture of the factory panel on the driver's side for reference.
