Hi again gents, I think I know the answer to this (based on my earlier questions about front suspension), but am wondering what is the conventional wisdom for leaf springs during a resto-mod process: buy new or dress up and reinstall the old ones?

I'm gonna guess they get tired after 41 years, but as is my ongoing dilemma, I didn't want to throw good dough at new springs if leaf springs last a billion years or so. They *look* old for sure.

And along those lines, where do folks like to get replacements generally?

Thanks and happy Sunday.
Tom
