Well, that's something entirely different, you are "replacing" leafs with new. If you re-arch each individual spring leaf {which is what I consider re-arching and thought that's what we were discussing} and reassemble the leaf pack as it was, you may get a couple of years {depending on how much you drive the car} out of the re-arching. They will return to a sagging state in fairly short order.
The above statement isn't something you were clear on, or I misunderstood, in previous posts.
In my opinion 200 bucks for a new set isn't all that bad, less work and wait, new bushings, no rusty or pitted parts etc.
