Replacing Hood

Hey guys, I'm trying to replace my bent hood but I'm sure what are the sizes of the bolts holding the hood to the hinges, and the ones holding the hood shocks to the frame. I can't go trial-and-error with my wrenches since I don't have any. I plan to buy some later but don't know whether or not to get SAE or metric. Any advice would be appreciated.

Thanks in advance.
