Who sells leaf springs?

Hello fellas, the bushings on my leaf springs (67 Newport Custom Fasttop) need to be replaced. I called the shop that did my NYer front end, and the VERY knowledgeable C-body guy there advises just to get new springs. He says there would be too many hours getting the old bushings out, and since the existing springs are 60 years old, it's better to just replace them.

SO, who sells them? Thanks.
