Hmmm . . . lot's of options, I guess. Cost-benefit analysis: what condition are the springs in generally? Still plenty of arch? Sure there aren't any other broken ones? Have you shopped replacement springs in your area?
We have a great spring shop in St. Louis. They will replace a single leaf, or a whole set. I don't think you'd want to pay shipping, though . . .
If it were me, I wouldn't replace one set of questionable springs with another set of questionable springs. Good money after bad. Your truck looks like a daily driver . . . give it new springs, you'll never have to worry about it again.
My two cents worth, anyway . . .
