I have a '71 coupe and I believe its "birthmonth" is April. I just checked the alternator housing after reading this and found these numbers - 1100950 42A 1C31 12VNEG. I don't have air conditioning and it's a 350CID/270HP 4SP. My question is this: if 42A stands for amps, then why is mine less than "gg82's" output of 61 amps? Is A/C the difference?

I looked high and low for the correct Q-jet (7028209-'68 427, std shift, Corvette only) for my '68. A lot of carb vendors would look up the number, laugh, and wish me luck. That's not very reassuring. I did eventually find a rebuildable core at a reasonable price with the correct numbers after a 2+ year treasure hunt. Many vendors who had one wanted $500 just for a core.

Okay. I'm looking and I see either an "I" or an "l" and then "13" and I'm curious how this converts to a date?
