I looked into that but b/c the housing is bigger from the 95, you have do some mods like grinding down my bracket. Of course wiring has to be upgraded.

The powermaster comes as a direct replacement, so it has same size housing. Just the wiring has to be upgraded.

Not my Powermaster! I did have to do some grinding.
I don't remember seeing any high output alts in the stock cases.

I have no idea what the alt cost me, as it was several years ago. I do believe it was more than ~$250.
I can tell you that it costs $100 to rebuild it. This big of an alt does not like to be rev'd to 6k rpm. It can handle it a few times, but eventually blows up.

the defogger (90 GT)also puts a big drain on my autometer voltage gauge. so does using the front windshield defroster or "mix" on any fan speed. fan speed #4 (highest) also drains my juice a lot as well. naturally the a/c does damage as well. i put in a 130A PA Performance alternator that i bought for $200 a few years back. the alternator install did require a couple minutes of grinding, very simple. also got a march 1000 pulley setup from PA Perf. (around $100)and they installed the alternator pulley on for me. i also upgraded the wire from the selenoid to the alternator to 4gauge as recommended by PA. ($40?) also replaced the pos and neg battery cables and started cables. ($40?)now my voltage still drops when i use the defogger, but not nearly as much as it used to. the drop is only noticable when at idle, anything over 750 rpm's and she charges great.
