Default Alternator number question

I have a mostly numbers matching 1970 350/350 that I purchased three years ago. I have removed the body completed the mechanicals and have it back in driving condition. One thing that has bothered me is the alternator, on the car is a 1100899 42 amp with a date code of 9J26. It looks like it was made in 69 with the extended aluminum fins on the housing cover. My guess is that I should have a 1100900 42 amp with a build date around March/April for a June assembled car. I looked at the Delco Remy web site and it shows the 1100899 was replaced by 1100900. So my questions are, could this have been original equipment or a replacement? If it is a replacement, what was the intended application for the 1100899?

As I've discovered, if you can find a suitable 1100900 they are expensive and I don't want to replace a good working original part for just a set of different numbers.

Thanks for any insight you might have to offer.

There's no evidence I've seen that an 899 was installed on any C3, the September 26 1969 date on your would be far too early for a June car in any case.

1100900 is the correct alternator for 350 and 390 HP 1970 cars without AC, or 901 for base engine without A/C.

Mike,

Thanks and I suspect you are correct. I was also hoping to discover what the original application was for the 1100899. If it was intended for a collectable car then it might have some decent value I can use to offset the purchase of a correct alternator. Do you know if such a registry exists? My 899 looks good and runs well, I know it's been on the car for at least 20 years.
