Super Stock Springs ( US or Mexican )

Also, add in:
These cars are 45-60 years old. So a replacement spring.... any spring is typically better than the 50 year old spring that’s worn out. “WILL the new spring hold up areas of a car for another 50 years?” Not sure as I’m not going to be around to find out.

SN: Harbor freight Chinese stuff seems better than the new Chinese stuff from “Craftsman.”
