There is a company on eBay offering a stock looking and mounting 135 amp alternator for gm vehicles. $110 plus shipping. Have one on my 66 442 drag/street car. Works amazing. Must use a solid state voltage regulator.
What do you consider "high output"? Is there a reason why you think you need more than 95 or 105A? There are two really easy, relatively inexpensive options. Any 12SI bolts to your existing brackets. You can get a 94A 12SI for a 1986-87 Caddy Fleetwood with the Olds 307. This is an internally regulated unit. RockAuto has them in the $75-90 range, depending on vendor. You can also get a 105A CS130 for a 1989-90 Olds Custom Cruiser with 307. This also bolts to your existing brackets with no mods. The CS130 requires only slightly more wiring mods than the 12SI. This one is about $80-105 from RockAuto.
I had an Oldsmobile file on my old laptop and I am trying to reconstruct it. I like the look of the small housing, internal fan, alternators. Thanks for the info.
CS130 from Amazon is $78 and change brand new. It was a bolt-in upgrade on my 67. Just add a different plug that fits it and make a couple jumpers to bypass the external regulator, do a search in the electrical forum for Joe P's instructions. On mine, I did have to rotate the rear housing 90° so the output post would clear the valve cover, YMMV.

I used the same alternator on my 62 F85. No issues at all for the last 11 years.
The square shoulder rides in the adjustment groove nicely so only one wrench is needed for loosening or tightening. It was kinda an accident that I found out how nicely it works. It was a temporary bolt to hold the alternator in place but it looked nice enough, I left it.
The only problem with the hardware store carriage bolt is the Grade Zero metal quality. Don't overtighten and inspect periodically for fatigue cracks. Those bolts are pretty much made of crap.
