Like someone mentioned above get the Marti report! They are as accurate as can be and having your cars build sheet would just be gravy. I had a 69 Mach 1 Mustang a year ago and got what is known as a Lois Emiger report which is the actual invoice from your car that has been at Ford since 1969. If we could only get this stuff on our Chevys.......
