Shipping is a huge cost, so closer to home might save money. I purchased new springs from Chevs of the 40's, they came from
https://www.oregonautospring.com/ . They had all the parts included need to install them. I replaced them for a better ride, there was nothing wrong with them, just a really stiff spring rate ( '37 trucks had heavy springs ).
I replaced the above springs with springs from Eaton Detroit. The Eaton springs have teflon ( type ) buttons on the ends for smoother quieter ride, had all the bushings, and sold me the matching u-bolts. It was a lot of money,but I was happy with the quality and ride. I had custom made spring rates, so the cost was higher.
