that is a 75 and that chevy emblem was part of the deluxe grill option with the chrome strips plus i believe the hood latch was a 75 only so check the opening in the grill cut out for the latch hope this helps
take small o ring cut and take small screw driver and slide in around the pivot post usually just one end will do it and that way you don't need to take apart works great mine have been in for 15years hope this helps
