wanted 69 alternator back that is finned
I have a correct front part of alternator for a 1969 442.
I need a back part that is finned, and needs to look like this.

Those two are different...you need the version in your SECOND picture. Note the different style holes/bosses for the brace attachment (which isn't used on either style).
The second pic is correct for a '69.
You probably already know this but others looking here may not.

Wonder about the listings shown for '70......none of them show a 37A or 55A with the internal regulator yet we all know a plain-jane '70 442 and W30 came with the 37A (internal reg) and the AC, etc versions came with the 55A (internal reg).
That only shows a 42A w/internal reg for '70 442 or W30.
Maybe the "suggested" replacement alts were different??

All 1969-70 442 and 1971 4400 show 1100544, which apparently replaces both 55 and 63 amp versions, again with the newer style back housing.
Finally, note that P/N 1846935 covers all 1963-1971 non-CAC applications (37-42 amp) EXCEPT the 1969-71 4400 series.
Bottom line, all 1969-71 442s did get the internal regulators.

This fella generally shows up at the Pate Swap meet every year. He has both versions of the finned back halves. All of his examples are nice, consequently they are not inexpensive.. $450 the last time I looked. I traded him an earlier NOS piece for a very nice later piece. Maybe you could buy the piece I had traded!. Good luck.

No - '70 open face alts are:
1100880 - 37 Amp
1100890 - 55 Amp
880 and 890 are the "stamping" numbers on the front half.....not a PN that appears in a book, etc.

Joe is correct on the 1969-71 alternators all being internal.
All the numbers in the 1972 publication Joe posted are second production numbers, and would not be the original alternator number on a vehicle from the factory.

But - is my thinking correct if I say that the '71 alts did not have a finned back half and had 5 spoke open fronts instead of 6 spokes like the '69 and '70 front halves? (Some other GM cars used this smooth back/5 spoke front after 1970)
Thanks

Hey Patton, you are correct. The 1971 alternators did not have the finned
"Diamond Back" nor were they open face like the 69-70 internally regulated models.
As far as the original poster, I may have a 1969 correct finned back. I will need to do some digging.

Thanks Devon.....that was my thinking but primarily based on similar alts used on some early '70's Buick Electras and Pontiac Firebirds and GTO's. Some of them have the 5 spoke front half and "smooth" back and I figured Delco probably did the same for Olds.
'71 versions on 442's seem to be a rarity.

Will consider #1100853 Alternator in any condition.
Thanks

Curious
How rare are these?? would a 1969 other GM have the same finned back??
When my alternator guy found me a correct number, open face way back.
I thought I was good.. why I really only need back half.

The finned back halves, both the '69 version and '70 version, are fairly rare.
Now you would think they'd be easier to find since they did come on 442s as well as W30's (and I assume SX cars in '70 as well) BUT the back halves have also been grabbed by Chevy folks to use on their setups. Some Chevy performance cars from the same era used the open face alternators (with finned back halves) so a Chevy nut with a correct stamped front half can use the same back half we use. Lots of cars/folks fighting over a limited supply I guess.
These things aren't typically priced cheap unless the seller is in a "philanthropic" mood or doesn't know how rare they are.
You may be able to do better, price-wise, than the $450 or so you'd pay the guy in Oklahoma (Funkwagon posted a pic of his business card) for a correct back half BUT he probably has inventory and your search would be finished. Considering that the internals are VERY common and cheap and that complete alts sell for $700 - 1300 or more, you can see where a price for one half of the rare case setup would run into the $400+ range.
Keep looking here if you have some patience and maybe someone will come up with a spare. If you want it NOW....call the guy in Oklahoma.

just my .02 - how many people look at the back of the alternator. If you have the front part I'm not so sure I'd worry about getting the back. Its the open-face front that really makes it unique and obvious when you open the hood.
#29
Agree with Funkwagon455 (aka - the artist formerly known as Heath ) - as I said in a thread over in the Tech Question section - "if you're gonna eat at the buffet, fill up your plate".
Watch people closely at Olds shows now. Used to be the owner would pop the hood and observers would see the front of the alt and notice the open face. Now they do that but pretty soon move over to the side of the car and angle in for a look at the back half.
One of many cool details and it's nice to have the complete package/look when it comes to these unique alts.

I agree but for $400 I''d say take your time and see what pops up. Both my W30s have the correct (possibly even original) alternators, back, front, numbered and date coded. I'm just offering up an option. Its getting to very expensive just to keep these cars running well, let alone collect all the correct parts.
