Hey Clark, welcome aboard! I'm some what suprized that they forgot to include the instuctions, but that does happen some times.
On the front bolts, there should be 2 shims and 2 rubber pads that have the same shape, a rectangle with a slot in it. Those go in the front, between the mount bracket and the frame, 1 of each per side. The shim goes on top. For the rear, there should be 2 rectangle and 2 round rubber bushings, along with 2 spacers. These are installed as follows- trom top-rectangle bushing,frame bracket,spacer, round bushing, washer, lock washer, bolt. The rectangle bushung installed so that the long side is parallel with the frame.
I hope this helps. I would suggest that you get a shop manual and an assembly manual, they come in very handy when you dissamble stuff.
