Lol, Junk Yard 3800 brothers.....it's a junk yard but not everything is junk. You'll save a bunch of money. And yeah there's a bunch of applications with the 125amp alt you just gotta make sure you get the right one (like 01'-05' Impala alt comes 105amp or 125amp) but I believe the 01' bonnie and Park ave both exclusively use the 125amp alt (some models even had a 140amp option I believe) but yeah they're all interchangeable where applicable
