I am just getting started with my restoration but since the truck does not sit level I know I will need to do something with the springs. The only local shop that does re-arching charges based on time but their estimate is more than either Jim Carter or Eaton. Disappointed with some of the off-shore parts I have already started assembling, I asked Jim Carter where their springs are made. They said they are made in Missouri. The Eaton springs are more expensive but I believe they indicated the price included new bushings too. Eaton will also re-arch springs but look at their website to see what they say about doing that.
