Also, I would highly recommend you check the panel fitment before assuming it's good and painting them. Most aftermarket sheet metal will take work to fit correctly and have good gaps.
The fitment of AMD fenders on my 72 would have required modification.
One side had a fitment issue matching the fender to the profile of the door. Hard to explain but the panel shape was too flat. Almost like the fender skin was on the bottom of the pile and was flattened a bit before the support structure was welded on. I would have had to bend it to get more of an outward bow or curve to make the profile match the door.
The other side had an issue matching up to the fender extension. I would have had to drill the spot welds where the outer sheet metal attach to the headlight bucket plate, make the necessary adjustments and re-weld. I painted mine and assumed they'd fit. That was a sad moment when I started putting panels back on the car.
In then end, I wound up purchasing an OE DS fender and had my rusty original PS fender repaired.
