Does anyone know the alternator for 1969 L68 427 a/c ps, ti
i am getting missed info on late builds for september 1969
1100825 stamped 9 ----or 1100900 stamped 0-----
thanks
The one found most often with those options during that time frame would be the 884. I think the 825 was being phased out by that time in 1969. If you are looking for a dated alternator as long as the date is correct either the 825, 882 or 884 would be correct. As PJO said, the 882 was said to be used on the L88 and L89 but could be on any 69 needing 61 amps. The 882 will be the most expensive to purchase.
If I remember correctly the Water pump pulley is a 3 groove the P/S is 2 groove the Crank shaft is 2 or 3 can't remember the alternator is of the solid machined design.
My '69 was built in June of '69 and has PS and AC and the alternator is a 1100882 61amp. This is an original factory unit.
Here is a picture of the layout.

I have been made painfully aware that the 882 is the second most expensive Alternator available for any Corvette. I believe a 1961 Big Brake car is the only one more.

I'm curious about your setup as mine is almost the same, but I think mine may not be correct. First off do you have a close up pic of your power steering pump, Im just trying to figure out if my pump on my 435 69 is correct. Also the bolt that holds your alternator on, the long through bolt, is that the original tapered flanged nut? I have that too, but I wasn't sure that it is original. Thanks
I took several pictures, but it is almost impossible to get a decent picture without everything removed. As far as I remember the alternator bolt is original, but I have had the car 49 years and have done several changes during that time.
Since you don't have A/C you probably will not have the tensioner pulley for the inner belt. You really only need it because of the A/C compressor. According to the AIM the PS pump number is 7808286 although I don't know where you could possibly see the number, you can hardly see the pump. You probably have the upper drawing of the belt configuration. Mine is the lower drawing.

Thanks for the pic, yes mine is not correct, but I have the correct one now as I bought a new pump housing the earlier style as mine had some later style, that may be original, but it never fit right, and yours looks correct as it angles away from the block. One thing I do notice on yours, is it looks like your missing one brace to support your alternator?? If you look at the drawing there is on more Z looking brace, which attaches to that main black upper support off the head
I see the brace that you are talking about, but I don't remember my car ever having that piece attached and I have had it a long time.
Now I am going to have to do some research on it to figure out if it was ever there.
I have done some research into this brace and checked many of the Corvette suppliers and only find a brace like that listed for '70 - '74 big blocks.
Don't know if 427's in '69 actually had this brace or if it was a late in the year addition. I don't remember my car ever having this brace and I am the second owner and had it almost 49 years.

I have that z brace on mine as well as the lower z brace, maybe sometime in your cars past a repair was done and the mechanic forgot to put it back on. If you need pictures let me know I can send some of mine.
The more I look the stranger things get. I have found a couple of suppliers that show a brace, but they show them mounted to different locations on the engine.
A picture of yours would help straighten things out. My car is 22453 and was built on June 19, 1969. Is your car a later build that might have a newer part added?
If not, I can't imagine that I have been missing this brace for all of these years. Doesn't seem to hurt it with it missing.

Im not sure how to date my car, but it ends in 509, but on the tag in the door jam it says B23 which would be Feb early 69. I will take some pictures tomorrow

B23 is September 23, 1968. A is August and it goes from there.
I have a 427 January 1969 car and 427 February car, both have the brace. My January car has been off the road since 1978 and is very original. I’ve owner the Feb car since 1992.
