Riveted lower firewall skin to firewall after removing shipping rivets. then counter sunk and riveted lower right hinge for lower cowl to fire wall. Tried to remove oil plug on engine to install oil restrictor which was back ordered but needed a hex socket which I'll have to get at ace hardware. The restrictor still won't go on because its a 45 degree fitting so will also have to get a straight female pipe to male tube connector.
