After hearing about them from John Balow at Muscle Car Restorations in Wisconsin (he's done several factory Super Stocks and light weights, as well as several OE Gold Certified cars for the Mopar Nationals competition) I did a story with Keystone in Brainerd, MN. They do OE chrome for trucks now, but they also have a huge restoration program that's top notch.
Amazingly, their prices are also extremely reasonable.
A couple years ago, my buddy had the bumpers for his '57 Ford Ranch Wagon redone, and they were under $300 each. I can't quote prices for them, but I can tell you my personal experience with them: I sent the rear bumper for my '62 Chevy Suburban to them last year. Both ends were bent in and contacting the quarter panels. There were a couple other dents, and the whole thing was twisted radially about 25 degrees (set it on the ground, and one end was angled down, the other angled up). Finally, there were about six 3/4-inch drilled holes in it, and a 3-inch hole cut in the center of it with a torch.
It came back concours perfect, and was $250. Now, prices may have gone up since then, but that's what it cost. Glass smooth, no grind marks, OE-quality chrome (meaning it won't flake off).
Additionally, while talking to the guy on the phone, I mentioned what it was for, and he right away said that those bumpers are unique to Suburbans (not the same as truck bumpers), and that the '60-'62 bumpers are different than the '63-'66 bumpers. He was right, as I had learned both lessons the hard way already. Who the hell knows that off the top of their head? They know their bumpers.

I'll be sending them the bumpers for my Duster, obviously.
