Hey Jason,
The mounting holes on the Replacement Master Cylinder Assembly # T2374600 are 5/16"-18 coarse thread. A 5/16"-18 x 3/8" hex bolt would likely be the best option length-wise and could be sourced from your local hardware store.

Hey Jason, how did things go with the new bolts for your master cylinder? Did the 5/16-18 x 3/8 hex bolts fit the mounting holes as expected? Your update could make it easier for others replacing a rusted-out cylinder too.
