I've seen a couple of photos of 50 Olds with what appear to be Chevy bumpers.

I like the look, and, if they would work, would be a less expensive option to chroming the ones I have.

Anyone done this swap?

It depends on the series you have. The 68 and 88 series use the chevy type body, and the 98 uses the Buick type body.
