motor mount bolts

[drew4x4]

what is the sizing of the bolts included in the competition motor mounts? i lost one of the lock nuts that went with it, and now, with the bolt holding my motor in (not driving! just sitting) i'm trying to figure out if they are a 9/16ths or a 14mm. thanks.

make sure they have those gnarly teeth on the head, so they don't back off on their own. I learned that the hard way, but got lucky I had at least one bolt in each.

yea, they are 9/16ths nylon lock washers.
