Just called and had talk with Standens Springs in Indianopolis, they are not building any leaf springs for AMC vehicles, he said they had sold all their old stock to a vintage car supplier in Michigan a few years back, couldn't remember his name. He gave a name of a custom builder in Omaha, NE. Anyway I described the problem with the aftermarket springs, he said they were most likely built in China, he said one of their biggest accounts, Neway suspension, which is used on over the road trailers, went to China for their springs to cut cost, anyway the springs on the trailers were sagging two inches while setting on the lot before being sold, so Neway came back to them as their spring supplier.
