Bolt size on drive train?

[dontknowwhatimdoing]

Bumped left fender with my left hand while mowing today. The fender moved. Found out I'm missing 3 of the 4 bolts holding the fender on and the drive train together. I stopped immediately. Could anyone tell me the size of bolt I should use to put this back together? I'm to scared to take the last one out, to take to the hardware store.
Thanks in advance.

3/8-16 x 1 5/8" for the left-hand side and 3/8-16 x 2" for the right-hand side. Use lockwashers with each bolt and torque to 35ft/lbs.

make sure the bolts holes on the left side are not stripped out, also make sure it has the dowel pins in the housing , ck for cracks in the final drive also, when they get loose that is when the trouble starts

The final drive housing is held by a total of 6 bolts. Along with the 4 through the fender, there are 2 more near the bottom. Make sure they are in place too.
