I got the chrome bumpers from Jim Carter. They are rather affordable with the 10% discount. The chrome looks good but time will tell how well it will hold up. The bumpers are approximately the same thickness as the originals. The one thing I don't like about them is that they did not smooth the stamped edges before chroming them.
I did not get the old ones rechromed because of the much higher cost and time investment, the potential difficulties in dealing with chromers, and the high variability of the quality of rechromed parts. In general I have not been happy with the work of local craftsmen, which has resulted in a number of redos.
