You want even more confusion? Here's what the 68 Chassis Service Manual says:
1100796 - All V8 W/C60 AND C75, all L6 W/C60 AND C75 EXC K19 and N40 (So... what the hell is C75??)
1100817 - All L6 W/K79 AND K19, and/or N40
1100814 Camaro 302 WITH C60. (Since when did the Z28 come with A/C!!!)
And according to the same manual, the correct starter would be the 1107368, BUT I don't think this is correct either. Mark will know for sure, but I think it's 1107365. The P&A shows it to be either the 1107365 or the 1107388, but I think the 388 is a service replacement.
So you can see that even GM documentation is totally screwed up when it comes to alternators and starters!
Mark???
