Pretty sure I have TG forged arms, came with the truck. I didn't know Marlin had a billet version, that would be sweet!!
If they are TG arms, they will have to be reamed out for the pins to fit. If you are one of the lucky people like me and have a set of billet arms that Marlin made, plug and play. You notice I said reamed instead of drilled because reaming is more accurate then drilling.
