Kevin Marti (martiauto.com) acquired ALL the Passenger Car/Truck/Bronco/Econoline FoMoCo records in the late 1980's when he found out that FoMoCo was planning to THROW THEM AWAY!

FoMoCo has none of this info any longer, but at one time was providing free build sheets (info obviously came from Marti), but is now charging a fee for build sheets.

Marti also charges a fee, which escalates, depending on how much info you want. Info known in the hobby as a Marti Report.
