UPDATE: DO NOT BUY THIS ALTERNATOR FROM AMAZON. THE PHOTO ON AMAZON IS MISLEADING. THIS IS A BRAND-NEW AFTER-MARKET FROM CHINA, NOT REMANUFACTURED BY DENSO IN THE U.S.A.

Sweet! Core alone is worth $75 to some.This is the best deal!
Now that I've actually taken one apart - easy, I can simply inspect/clean/replace brushes myself.
Good to have a Denso frame.
Thanks!

Auto parts store alternators only last 4 to 5 years in my truck, then have low charging. Finally bought an OEM Toyota rebuilt one Denso and been 5 years and still outputting volts like new. The real issue is not the cost of the cheap parts store crap, but the time and difficulty installing the alternator up from the underside. Every parts store one I got, the bottom bolting bracket was too wide to fit the engine mount bracket. It had to be ground down to fit. The OEM Toyota one fit no problem.
For everyone needing to grind down their mounts, this might save you some time:
In the process of replacing my alternator, I discovered the lower mount is designed to be somewhat adjustable. The bushing in the mount is pressed in, but appears to be designed to move when tightening the lower bolt to get a perfect fit with the alternator. With the right size socket and bolt, you are able to pull it back out so there is no grinding necessary. I originally had the opposite problem; my alternator was too loose. I fixed it by tightening the bolt without the alternator installed until the bushing popped loose and was able to smoothly slide again. It was then too tight to fit my new alternator so I used a socket and bolt to pull it back out again.
The Toyota/Denso alternators that fit perfect probably were made with the original casting, while the parts store alternators probably made their own casting, along with their own lower quality internals. It is very frustrating how many low quality parts are out there these days.

You might try using the 'Notify Me When Available' button on Rockauto. Not long after I bought mine, I got an e-mail that they were back in stock. I checked and they are now out of stock again, but they might be getting just a few at a time.
Do you remember if the bottom bracket was threaded when you removed the alternator, at least the back hole? The pivot bolt on mine had a rounded head so I grinded it off. I can't tap the bolt out so it is either seized or threaded but I can't tell.
The lower bracket is not threaded. There is a nut on the end of the bolt. Try turning that nut while tapping out the bolt. That might be enough to break it loose.
Got the alternator from DB Electric via Amazon it is not Denso Remanudactured in U.S.A. as pictures in posting show.Back to Checking McGeorge, Lakeland Toyota, Toyota Parts Deal and NAPA.
that sucks. the alternator i received did not have a "made in china" label, on either the box or the alternator. doesn't mean it wasn't made in china, as there was nothing on either to indicate where the alt was manufactured/remanufactured. so far, so good.
just placed an order for my blown headgasket and associated parts from mcgeorge on thursday. so far, the order has not been shipped. perhaps i should have ordered from toyota parts deal.

No worries. Got my Denso, remanufactured by Denso in the U.S.A., from NAPA for $142 + tax. Best deal because I would not have to worry or pay for shipping the core.
I also like McGeorge Toyota. Got me better prices for the past couple of purchases compared to Toyota Part Deal. So to date, I compare total cost between that, Lakeland and TPD.
Reman by Denso in the U.S.A. $143 Plus tax from NAPA. Excludes core refund.

I digress, take your best total delivered price to the local Toyota parts counter it will surprise me if they can't match or beat it.
Alternator Runs Hot and B-Terminal Resistance to Ground
I would like to ask for your opinion and/or actual experience about the following:
1) For the first time, I felt my alternator too hot to the touch @ 150°F. I think this is because it is working hard; my battery is low because I ran on battery power only for a few days as I waited to replace the alternator. Other Toyota manuals mention temps up to 239°F. Have you experienced this? Thoughts please?
2) When I picked up my rebuilt Denso alt from NAPA, I immediately measured resistance from B-terminal stud (output) to metal housing and got 70k-ohms. IIRC, the last time I measured it on an older alternator I got very many meg-ohms - or maybe I just forgot. I expect that to have a very high resistance to ground because of the rectifiers. May I know what resistance you get with nothing connected to that B-terminal stud?
