bad alt
 

i've got a bad alt. needs to be changed and i have the replacement, its from a 94 pro. im fine with the 12 and 14mm bolts on top and bottom and the plug but in not sure what the best way is to get the belt off and back on?

there will be an idling pulley (i think thats what its called)
its about 2-3 inches wide, when you turn it (with a wrench on the bolt) it will slide, loosing the tension on the belt, then you take off the belt, put you new alternator back on, and repeat the process, only in reverse.

its much easier than it sounds...trust me
