I bought an AMD 67 (only) front bumper for my '67 just to start showing the car. It is the only one with the extra hole for the outside lower bracket mount. For $95 w/discounts, it is flawless. Smooth surface, excellent chrome and fit. But....on the inside and if you know where to look, it has a vendor's code engraved lightly into the metal. If the chrome should fail years down the road, I will get this re-chromed and will ask to have the engraving removed because the core is so good.
Now....the rear bumpers....that's a completely different story. I have yet to find a vendor that sells a halfway decent bumper. The fit is good, the chrome is good, but the metal surface prep can be wavy. And some have the center bracket welded and chromed. I have an original that's in good shape and will send that out eventually.
