Rick,
Make sure to constrain the 'assy section' part to the default planes and or axes of the assembly workspace OR RMB click on it and select Anchor Part from the pop up menu.
Then see if the offset reverse will function for you.
I also noticed that you changed the bottom chamfer of the pin to match the one at the bottom of the hole. they are now both the same angle. IF that is the new design then a Fastener constraint will mate the parts together on their faces. That also means that the dimension given on the Sect T-T drawing is no longer valid.
