Has anyone been buying rear leaf springs from ESPO Springs n Things anymore? http://www.springsnthings.com/ There is some reference to them in the FAQ section of this site.
They obtain their American Steel from elsewhere and assemble the springs to factory specs. They are much less expensive than NPD and Eaton at $215/ MATCHED pair for the 4 leaf HD springs. The lower price is scaring me a little. Of course they come painted black like every other spring now, so to make them correct, you need to disassemble them and powder coat or re-paint them if you are going for concourse resto.
