Doing the same to my 79 cruze wagon , but I like the 76 grill and the old look , not done yet but I used 76 fenders , along with the hood ,(you can use the stock hood release ) 71 to 73 did not have the hood release and the hood will not fit right because the radiator support is move a few inch,s forward , I am using the 77/78 front bumpers because I have them and very light , you can use the skinny ones but will have to make brackets to hold them, and the tail lights you will have to use the larger 77/78 tail lights , the 76 to 71 down the holes are smaller where the bolt too,
