    Can you measure from center of the pulleys?

    I saw the Atlantic for the first time after dinner in that restaurant in the Prudential Building, so I couldn't tell if it were "Dirty Water" or not. I was on me way to deliver my '57 Seville to Framingham. Story there. I may tell it to you when you are older.

    My 1972 Cpe DeVille (DeVille convertible-to-be) has the 472, and my temporary A/C cut-out (Gonna need it in the summer in the desert!) is: Front fan pulley >Alt--15375/11AV0955 (prob. Dayco); Crank>P/S--47515/11A1205 (prob. Dayco); Crank>Smog Pump--7453/110A1150 (Gates). It has been working for a while. Hope this helps you out. BC

    I have no smog pump. So I need to know a '70 non-ac belt size.

    The Harbor is not the Atlantic, it is a bowl the Atlantic throws up in. : )

    Rockauto sells both size belts... I know because I accidentally purchased the wrong size. According to their site, the Goodyear belt without AC is 47" and the belt with AC is 59.5" (the AC Delco belt is 60 1/8").
