I thought I had some pics of the white & blue '68 interior but can't seem to find them.

If you check your fender tag there will be a "W" under the "U" (for "white" - Upper Door Frame paint) on the second from bottom line. The UDF, seats, door panels, inside rear 1/4 panels, panel between them, convertible "boot", & armrests should all be "white" in varying shades. The carpet, seat belts, kick panels, dash, dash frame, A-pillars, interior windshield header (your garnish mouldings) should all be varying shades of "blue". Sun visors??

1968 only combiination (in '69 the UDF was blue on the P6C interior)
