Buddy bought a car that they previous owner installed an AMD roof skin on it incorrectly. It has to be removed and replaced with a new one. AMD is out with no delivery date in sight. He found a Dyacorn in stock. Any issues with that brand?

I have a 72 Challenger that I had to replace most of the sheet metal on including the roof.
All my sheet metal is AMD. I had terrible luck with other brands fitting correctly so I spent a lot of money learning that AMD is the only way to go.
I don't know the brand you mention but my suggestion is if you can wait for AMD, I would wait. A roof is not the piece that I would want to wrestle with to make fit right.

I run a restoration shop, AMD panels usually fit real nice, maybe some light massaging , all other panels, a lot of heavy massaging and sometime still don't fit, your choice but I would wait.

Well thanks for the advice here but it’s too late for my bud. He ordered a dynacorn roof skin from a place that had three of them in stock. He ordered it from a place I’ve never heard of. They said they sell AMD as well but we’re out and would not get any for several more months. He claims that he has had no complaints from customers with either brand. I guess we’ll see. It’s too bad that the AMD was put on wrong. It was just an obvious mistake once you started looking at the finished product. It was not because the part was bad.
