Digging around on ebay, found all I need to sort the spring out for $150. I was to unsure about the 5.5in cast iron blocks that where found, so went with the 4in steel bocks. The only ones I was finding that where 3in wide with a 9/16 was for the new super dutys. I also found nos zone 5/8x18-1/2x3-5/8 for cheap as along with some top plates.

After some uming arring, to gain some lift in the rear I cut up the 3 long I pulled from the driver side so both are a stack of 11. Will make another 2 leafs for the bottom of the stack later, I have to pull it back apart to put a bigger bolt in it. I thought 9/16 pin on a 3/8 bolt was correct but was wrong, its a 7/16 bolt that came out the stack.

I also found why it road like a hard tail but is not the only issue I found, the rear u-joint slides around in the yoke. Glad got 6in lift shocks for the rear when I got the 4in ones for the front.

So now have matching spring stack, it rides a lot better now with flex in rear.
