December 11, 200520 yr Ok, so I had the old tech big case 100A alt for a '79 Cutlass ... and it didn't want to go on like I saw in the write-up, so I went to the parts store to see if I had the wrong one, and he found me a 94 amp alt for a '85 Cadillac Cimarron with the 2.8 V6 ... $70 with a $25 core AND it it the SAME size as the subie one for my EA81!! Just thought I would share the news :cool: Goto www.oreillyauto.com and look up a '85 Cadillac Cimarron and from the list of alternators look for the Ultima Remanufactured 94 Amp Alternator Part Number 01-0221 and yes, a purist would make a spacer on the left side to fill the gap between the mounts, but I can tell you, otherwise it is the EXACT same case size and distance between the mounts. Enjoy!
December 11, 200520 yr nice.. will most places take the original ea81 core, even though its differant from the alternator you bought?
December 11, 200520 yr Will it work on an EA82? I have never seen an EA81 it's the same alt. for ea81/2 I just scored a 90a xt6 alt, it fit in my toolbox while I was at the j/y I then took it to autozone to have it tested, works fine!
December 11, 200520 yr Where I live an alternator from the junkyard would not be worth a trip to jail but thats just me. Here they range from 12-35 and occasionally they add a core.
December 11, 200520 yr hmm guess i need to get this xt6 alt tested, well go test it myself at work, and if its good swap my pulley, if its bad, well, go get the 85 cimaron alty off the shelf, add my employee discount, scratch the core and off i go,

December 13, 200520 yr Author ACK!!!!!!!!!!! Ok ... I screwed up ... I just went and actually TRIED to install this alt tonight ... the ears are actually about 1/4 inch too narrow I got it work but it is ugly!!! No pics, I don't wana break the camera! (I can take some if you ask nice tho :-p ) I had to not only flip the alt left to right, I had to cut the ear to the right to the point that the bolt isn't inside it, it's right on the edge of it, in other words, untill I get a big fender washer to keep it from being able to slide off, normal vibration will cause the bolt to slide off the ear ... sorry ... I was so sure when I measured it .... I'm sure there is one out there, just have to sample some more GM alts till we get one that matches the distance between the brackets. On a good note, I was able to use the stock belt, and it only took me about 4 hrs to figure out how to make it work ... if not for the off-set, it would have only required shaving off about 1/16th of the right ear. good luck .. I don't recommend this alt, but there has to be one closer ... Ok, well it turned out to not be as big a deal to keep the bolt on as I thought, but still requires considerable modification ... so I will look for annother that is spaced out a bit more ... and here are the pics ... ***WARNING!! POSTER NOT RESPONSIBLE FOR BROKEN SCREENS DUE TO THE INCREDIBLY UGLY PICTURES YOU ARE ABOUT TO OPEN!!*** Notice in pic #4 that the bolt is centered on the far edge of the ear instead of inside it. I have a large washer keeping the bolt from being able to vibrate off the ear, it might work, but I don't really trust it. Also, for those of us with A/C, you have to remove some of the back rib of the mounting bracket to make room for the bolt on the drivers side bracket.
December 15, 200520 yr Author Yeah ... it is isn't it *hide* I'm gonna get a list of GM V-6 cars that have high amp alts and check the junk yard and see which ones have the correct spacing between the brackets and go from there ... Oh well, at least it works ...
