Alternator advice
I have the original Delco Remy 10SI 42 amp alternator for my 1970 non-AC 350.
I took it to AutoZone to get it checked out and was told it passed. I then proceeded to clean it up, blow out the dust with the air compressor, and carefully paint the fan, pulley, and housing. I thought that I should test it again after doing all this before I put it on, and--of course--it failed the test. I noticed that it kind of squeeked when it turned, so I'm guessing the bearings are going too.
The only rebuild kit I found was this one:
Delco Remy 10 SI Alternator Rebuild Kit 70 Amp
My question is, should I:
1.) Get that rebuild kit from ebay, eventhought it says 70 amp and my housing is stamped "42A".
2.) Take it to the alternator shop recommended to me by the guy at AutoZone.
3.) Get some other rebuild kit that I don't know of (that hopefully someone will tell me about).
or
4.) Something else...
Thanks!

You can just buy a stock CS130 and get a pigtail adaptor, its much more reliable and got more power than stock 10si, and best of all, it will drop right in with no modifications.

That's exactly what I was going to suggest. I have a paper on that install if you decide to go that route that may help you out.

I went for the CS144 option which is (supposed to be) better than the CS130 option with more amps at idle and better cooling of the alternator.
I took this route so that I could accomodate dual electric fans and a small amp and stereo and have enough power in reserve for any future upgrades.
Had some minor issues with fitment however nothing I didn't sort out myself without any fab work necessary.

I used their kit to upgrade my 42A stock to 80A over 6 years ago. No problems and runs my dual Spals just fine.

It seems to me that a question like this does not even get asked unless someone is trying to preserve a numbers matching car. I would go ahead with the internals upgrade. I would not take it to a rebuilder unless they are restoration specialists, cause you won't ever see your matching numbers/dates case again. The question then becomes how comfortable you are with installing the kit yourself. There are some writeups on how to install the kits. Check Zip or Mid America for tech writeups.

So, can anyone recommend a rebuild kit, or is that ebay link I gave a good one? In doing this frame-off, I think I've rebuilt just about everything (engine, trans, steering box, wiper motor) so I might as well do the alternator myself too.

Delco Remy 10 SI Alternator Rebuild Kit 70 Amp
Is there any disadvantage to getting a 70-80 amp kit instead of the regular 42A? I understand that as the alt produces more current, heat goes way up...and the stock alt fan probably isn't meant for it. But I guess since I have no electric accessories, (and as was mentioned in the electric water pump thread) I won't ever be producing that much current/heat anyway...

[QUOTE=rick1500;1562386672]Thanks for all the replies! I haven't been able to get back to the forum until now, otherwise I would have mentioned ealier that--exactly as 71rdster noticed--I'm trying to keep everything as original as is possible/practical...I probably should have mentioned that upfront...QUOTE]
In your case I would store the original alternator for posterity and buy a Delco rebuilt from Advance, O'Rieleys, or your local Delco store. You can upgrade on amps a bit (like a 70A 334-2138 or similar), it won't hurt anything. Just eat the core charge, it won't be much. You will have an alternator that will go another 36 years.
I have no use at all for the CS130, if you do the upgrade go with a CS144. It is much more reliable.

Since the extra amps will be of no benefit, why bother 'upgrading'?

Exactly...Ideally I wouldn't be upgrading, but like I said I need a new alternator, want to keep the original, and cannot find a rebuild kit that isn't 70-80 amps (any other recommendations?).
I suppose I could keep the original in storage and buy a new one like markdtn said, but I think in the case of my storage situation, the original would be safest if it's on the car!
I think I'm gonna go with that ebay kit if nobody says it's a bad idea. It includes bearings and is only ~$40 after shipping...

Most rebuild kits do not include new bearings, only the electrical bits and pieces like new brushes and diode ***'y. Usually 20-25 bucks
The one on eBay includes bearings. I'd buy it and flip a coin on whether to install the 70 amp stator or not.
