Front spring shackle help

[LDO]

I purchased this rebuild kit for my 57 front end. http://www.classicperform.com/Store/.../5559SHK-F.htm

I am a little concerned because it doesn't look like the old stuff I removed. In particular, the threaded pins. My old stuff had nuts on the end of the threaded pins. The new pins don't extend past the shackle plates. Am I to assume that the center (long carriage bolt) bolt keeps the shackle plates squeezed together and that's it?

This kit didn't come with any instructions so I got nothing to reference.

Also, is anyone familiar with torque values for the hardware on the front axle? Didn't find anything in my assembly manual except for the ubolt nuts.

Thanks in advance.
