    What's the best way to make this flow back how it was. Pie cut and fill? What have you guys seen or done?

    When I did a chop on a Packard, changing the roofline a lot, I had to remake the corners of the quarter windows. I made a wooden form, the right radius, rounded it out to match the roundness of the rest of the window surround with grinder and sandpaper, and clamped and hammered a piece of 18 ga steel around it. This way I could be sure both sides matched, and I had nice pieces to patch into the opening.

    Pie cuts and welds would be the standard route. But I like chopolds way.
    Some times it is harder to make something fit than it is to make something new.

    Just like Chopolds said, make a hammerform out of some MDF and make new parts. This is a simple piece to make this way! You can use a router to do the radius. Hammer your metal a little at a time until you get it formed.

    Even if he just cuts a pattern out of some s**** plywood or chipboard to get the correct curve for slice, spread and fill that is what I would do. I've seen too many quarter windows on chops that were just a bit off from each other.

    Choptop50 you want that line to flow smoothly all the way from the back corner to the front corner of the window so that when you are done the quarter window looks like it was designed that way at the factory. I think that is your plan but lately I have seen some quarter windows on chopped tops (including one on here yesterday) that are just done all wrong and end up having no flow nor appear to have much thought put into them.
