Awww, don't lose the A/C....just get a bigger alternator. I'm sure you can find other toyota units that'll fit, with minor modifications. That way you don't lose A/C on those hot days. That's one creature comfort I refuse to sacrifice. Ironically, it's very rare that I actually use it, but when I do, it's like not using it, and having a PS pump on there
(my justification to myself)
