I think your picture shows the pins installed screwed into the tranny and sticking into the bell housing. You may have big trouble getting the tranny all the way in if those guide pins hit the clutch, let alone getting them out after the tranny is in place. Screw them into the bell housing (top bolt holes) and slide the tranny over them. That way there's lots of room for getting them out after the tranny is slid home.
