If you're looking for something in the August-September 1969 range. my guess is you'll be OK with a 1100884 as well. You're in the general time frame when the the 1100882 was phased out of production and the 1100884 phased in.
If you want an original alternator, you're going to be in for a long wait (or you need to be incredibly lucky) as these alternators don't turn up for sale that often... Figure on $600-$700 for a core and $1000 or so for a correctly restored unit ready to bolt on. I have some contacts, but my guess is that you've probably already contacted them.
If you are in a pinch short term, I know that there is a reproduction front case for the 1100884 that has been floating around for a year or so... Date codes are supplied by the buyer. It looks pretty darn good when combined with an original rear case. Don't know who is doing them, but I can probably find out if you're interested in going that route until you can find an original.
