Any reason this alternator would not fit in my truck?

Oh, and as far as any wire changing, it never hurts to go up a gauge in wire size but you shouldn't need to. The 105 amp uses a 160 amp fusible link in the lead to the battery, so even if you draw the full 145 amps it won't blow, but still offers protection.

I don't think Kris will have any wiring issues.http://truckmodcentral.com/forums/showthread.php?t=5295
