55.2-59 Just bought a 57

[mgchevyparts]

So I just got a 57 small window. Rust free body from Calif. All original suspension, has a 350/350and that's it. I'm liking it just the way it is and I don't want to do the 2 year replace everything routine. It drives very well, stock straight axle, drum brakes etc. I was surprised that it turns nicely and stops straight with original stuff. The only thing I would kind of like to do is maybe lower the front a couple inches. I saw some 2.5" lowering leaf springs on Brothers website. So my question is, do those lowering leaf springs work well, any better pricing then Brothers?
