Hi, I'm a new member and, after being away from Z's the last few years, have just bought a 1971 240Z with production date 2/71. I plan to replace the current aftermarket radio and repair/replace the clock. My research on the radio points to a Hitachi TM-1081ZB(S) ... where the "S" is for seek. (Were there non-seek as well?) Is this the correct radio? For the clock, is there a certain model of the Jeco that would apply to my production date? Thanks, --Thomas
