i need a new alternator...is this an easy job to do on a 87 2.7L manual?? im skeptical on the belts and how to tighten them. other than that it looks pretty simple. do u guys know where i could get a decent rebuilt alternator?? i was thinking discount auto or autozone but whats a good place to go to?? the reason why im tackling this job myself is because a mechanic asked for $320. i thought that was a lil steep so here i am.... thanks for any help.
