The company is Sioux Plating in South Sioux City, Nebraska phone 402-494-2477. I misplaced the name guy (I think its Scott) who handles the rechroming, just ask for the guy who handles rechroming classic car bumpers . I may be off a little on price -it might have been $300 for each - the last ones I did where 62 California one piece bumpers, my bill is put away somewhere. They do not do potmetal like tailights or outside vent window frames..
I/we have some 62 Chevy bucket seat chrome that they are doing about to take bumpers to him and window frames(the ones that are chrome steel).
When you talk to him tell him that I told you to call. I have 62 Chevy 3 piece cores that I could give him to do for you a very very reasonable price for the cores.
I could check them for you when done.
I noted lots of comments in this post on the repro bumpers- so more detail from what I said before. The joints do not fit right, way to thin compared to solid originals, chrome not close to rechroming quality. They did not fit the car correctly by the fenders.
