Good point Jerry. Mike's use of logic is refreshing and makes perfect sense. However, like with most topics First Gen, the proof is in the pudding, and or better stated; in the stats. So, your recommendation above all makes the most sense.
I know for a fact there are members who have cars with similar build dates as mine. I also think some of them were built in L. A... Whether or not they will contribute is another matter. If they do, we can as they say kill two birds with one stone. Relative alternator dates as they relate to the cars build date, and any consistencies with regards to the build date of my car and weak stamps? Hope they do contribute. I think a lot of us can benefit.
In addition, given what's been discussed and the regularity by which these alternators must have been pulled from the shelves, wouldn't it be safe to say their dates should be very close to the actual build date of the car? Say days to 4 weeks tops?
Sure need some folks with the 1100843 who know theirs are original to the car to hone in.
BTW...like your avatar Mike.
