Yes, it has been a while, but I think they are the same body style, and if they are yes they will.
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
No, the body was updated, so it won't line up with the headlights/fenders/grill.
yes, they are the same exact cars the only differences are the front headlights and grill and the tail lights otherwise the cars are pretty much the same. so yes, a 73' nova hood will fit a 70'
I've seen a 572 fit into one with no modification to the existing fenders or hood 502 Big Block
No
Yes, but you will need 1999-2000 head lights, fenders, grill, hood, and front bumper.
Yes. The basic front fenders are the same and interchangeable for 70-74 Novas.
No, they are not a direct fit, the 96-98 front clip (hood, fenders, bumper, headlights and grill) is different than the 99-00 front clip
No, they're 2 different grilles
No, they're 2 totally different grilles
No it will not. It can fit, but you will need head lights, fenders, hood, grill, and front bumper from a 1999-2000 Civic. Transmission doesnt matter.
