sorry for the noob question.. having never looked, I have no idea where its marked. where are the bolts typically marked? Or does it vary from manufacturer?

Thanks

it varies with manufacturers, just look around and you'll eventually see. typically there will be a mark on the actual BOLT at the 12 o clock position. and on the carrier on the back side (closed side of the receiver)
