Leaf Spring Suspension

[Stevetoxic]

Like some of the others - I'm following with interest.
My 59 came to me with a front disc conversion, I added Posies 3" drop springs all round and a CPP400 power steering conversion.
Its a really nice drive now - sits on the motorway at 70-80mph no problem, stops and steers straight.
I'd like the front a little lower, but do not want the expense or work involved in an independent front conversion.
There used to be new drop straight axles advertised (CPP ??) but not seen them for 55-59 trucks lately.
