No. Those didn't happen till 1979 I believe on Volares and ASpens. Mine came with a Holley 1920.
Then I bought a 2bbl manifold and put a Weber 38/38 on it, and it was great, but I didn't want to cut that beautiful carb up for boost, so I went to a Holley 350 since the information for modifying them was readily available.
The fenders do. The hood does. The doors do not. 4 doors have shorter doors. The two door has longer doors. The windshields do not interchange either. 4 door windows sit up higher, so basically nothing interchanges besides the mechanical stuff, and the front fenders, bumpers, hood, etc.
