alot of it is different. alot is the same. anything you're not sure about someone here or on the "L" can tell you the difference before you tackle it. the right book for your car would be a plus though, o'course.

there are a lot of body differences, such as marker lights, doors/hinges, interior, and hood latch, and the rear springs/rearend perches are different. if you have mono-leaf springs, it is likely still a 67 rearend, and should have a radius rod on at least the right side... though it's probably been converted by now... camaro/nova rearends are different too, but bolt right up, so....

dash lights is probably a ground. use the search function and search 'tech help' with 'dash lights'/subject, and you should get a few hits.
