On the water pump side you'll need 2 spacers that fit into the frame. I not sure of the size as I haven't had the stock sliders, err bars, on for 2-3 years.
You can use al the bolts except one on the right side at the top you will need a spacer 3/4 inch long a a 2 1/2 inch long bolt. Any hardward stors should have a spacer/bushing that will work.
