If reading the Ford 1980 body-chassis manual correctly, the paint code 3F stands for a color of Light Med. Blue. The 64B body code stands for 3 Door Sedan. The interior code HB stands for vinyl low back bucket seats with a interior color of Wedgewood Blue. In the VEH. IDENT. NO., the 0 is for 1980 (I believe), the T is for the Metuchen assembly plant, the 11 is a body serial code (same as the 64B described above), the A is for the 2.3 engine, the rest is a consecutive unit number. No clue if this nice Pinto is rare or not.
