Body off restoration or not ?

[SS427]

That really depends on a lot of variables. Concours or driver quality. New interior or use the one you have, etc. If I did the car for myself by myslef using all the NOS parts you say you have, not rebuilding the drivetrain and restoring the chassis and body I would say very easily $40k plus especially when you include bodywork and paint. Keep in mind I never restore anything "just good enough" and everything has to be perfect for me which means it costs more. Sadly they barely bring that if even that but that's why I say if you are doing it for you and not to flip it is a moot point.
