Looking for new leaf springs

My springs on my 67 are from Espo, and they are considered 2" over stock. The wheels are 17", so don't let your eyes deceive you. SS springs will make it look pretty jacked up in the back, but not much more than in the avitar picture you have. I know a lot of people were complaining about SS springs in the early 2000s after they started making them in Mexico. They lost their arch quickly. I'm not sure if that problem has been fixed or not.
