Leaf Springs,Replace or recondition?
Well seeing how it took the original spring pack 40+years to sag I'm not gonna worry about it. A proper re-arch only re -arches the eye leaf and replaces the leaf pack,all for a lot less than any fancy internet store.
Plus there is that local job's thing I mentioned,but hey in this economy that doesnt matter at all.
Either way the op is getting new. I'm getting mine done local,save a ton of money and support my neighbour's job. Oh and I'll laugh all the way to the bank. The last quote I got was well under $200.
