10 year old Goodmark quarters

I've used both and the only difference that I've noticed were that the AMD parts needed a little less flange trimming than the Goodmark units, but they both needed a reasonable amount of adjustment, punching, drilling and cutting before I could install them.

The Goodmark panels that I put on the superbee had incorrect bumper relief areas that I had to move up about 1 1/2" to copy the originals.

All you need to do is keep the originals around to note any differences and cut/ adjust the new ones as needed. Every bodyman is going to give you different opinions, depending on their prior experiences.

Truth be told, they will work and if you can get them for cheap, do it and save the additional money for something else.

No matter what, you will be doing bodywork, welding, etc., on the car, so just get what you can for cheap.

I've made most of the patch panels that I've put into my restorations from scratch. It does not matter where the metal comes from. The quality of install and fit is what matters in the end and any stamped metal is going to give any bodyman an advantage over having to pound 18ga by hand. AMD still puts MADE IN TAIWAN stickers on their full quarters, just to give you an idea. They brag about weight, which can help in some ways, but that all depends on what you want. If you are a race car guy, that could be a bad thing.
