I agree with the posts above. The interior is the hardest to get for. The only thing they make is the seat covers and door panels (and they aren't that perfect of a reproduction). All of the rest of the interior you are on your own for like the steering wheel, horn button, radio, carpet, headliner, etc. From the description you have of the car, you might be putting another $7,000 or $8,000 into the car. So you would have $16,000 into a car that might only be worth$17,000 when finished. Now prices are going up on the Anniversary cars, but if it is a 403 automatic car, they are run of the mill. If it was a 400 4-speed car, then I would say go for it.
