no frame will fit a nova as it's a unibody.
Well in my 68 you lift slightly on the front of the seat and push back there is a clip it sits in underneath and u have to push back till u can raise it up. The back cushion is same principle. Assuming for bench seat.
Yes - the 68-72 Nova hoods, door skins, fenders, quarters fit 73 and 74. The only difference is the front clip (grill, lights, bumpers, front windows).
No. The subframes are not the same. The 68-74 had the steering behind the crossmember and 75 and up had it in front of the crossmember.
68 to 74 Chevrolet Nova (Chevy II). 72 to 74 Pontiac Ventura II. 72 to 74 Oldsmobile Omega. 72 to 74 Buick Apollo. 2 door or 4 door to match your car.
Yes it is, the nova is also useable in the camaro or firebird,I put a 73 nova subframe under my 68 camaro.
Yes. That body style came with a big block version from the factory. Also, remember that your Nova, is the same as a 67, 68,and 69 camaro, which could end up saving you some money, as Camaro parts are more plentiful.
Yes. The only difference besides the inside door panel is the 73-74 doesn't have the wing vent window like the 68 -72.
The bench part, with a comfortable, heavy-duty back pad, is 68 inches in length.
you can have anything from the 6 cyl. up to the 396 v8 in the 68 nova.
68 to 75 nova, the same body style will work.
