Brad,
Thanks, I find the assembly manual confusing at times. I now know that I have bushings for the shackles, and the rest of the hardware goes to the front mounts. I don't have the plates you show in your photos, either threaded holes or through holes. Would it be possible to give me the thickness of those plates and the bolt lengths, I assume the length and width of the plates corresponds to the shackle.
I can have the shop at work make something up for them.
Thanks,
Mike
