i like the keystone bumpers that roseville sells, not sure if they have them for a b-body and i think you can get a 10% off discount code.
Keystone bumpers are AMD products, Keystone was only re-chroming rejects that didn't pass visual quality inspection (same nickel/chromium plate finish as AMD, no copper), from what I hear Keystone stopped this operation, but of the number of AMD bumpers I've purchased, I have no issues/complaints, as long as your looking for an OEM appearance, you want triple chrome candy looking chrome you'll need to vist a chrome shop...
here's an unsolicited opinion of the AMD B body bumpers ....
