PHS charges $45 for fax back service and is followed up by the docs and AMA specs mailed out to you within two weeks.
Here's something interesting I e-mailed Chevrolet Customer service to inquire about the dealership where my 70 Z-28 was purchased. They called me that evening and requested my VIN number. They sent me a what they called a Restoration package that includes the AMA specs as well as the GM doc that shows the vehicle specs, part numbers and capacities. The same docs that you get with PHS except the factory to dealer invoice.
Now why would GM keep that and not the invoices
