Hi Michael
I just got 3 of the four pieces on my car re chromed. The originals were straight, with slight dings which was my reason for rechroming them, but no rust. I didn't send them out, but got them done here in Denver. Overall, I am quite satisfied. The process they used, however, is not the triple chrome generally used on concourse cars (the first copper step is omitted). They turned out fine though. I was charged $200 per piece, which is only a bit less than the cost of a repro stainless one, but I rest knowing I have my originals back on the car. I suspect triple show plating would be quite a bit more.
So, depending on how much work yours would be to straighten, I would recommend keeping the originals. Just MY thoughts though...
