I've got my previous set of Dobinsons springs available... Fronts have approximately 23k miles, rear's have approximately 25k miles on them.
C59-300 Front Springs - "Stock front end load, 1.75" lift. 385mm height, 586LB"
C59-327 Rear Springs - "200-400LB heavy rear load weight, 2" lift. 410mm height, 271LB"
$100/pair
I'd much prefer local pick up, I'm just south of Baltimore, MD (21060); shipping could be arranged at buyer's expense
