what do you have? 4 banger or 350HP v6? (who am I kidding

)
but seriously, if it's the 2.8L.. We are going to snapp some manifold bolts... and we are going to have to drop the engine to do it right. A shap would charge you at least 4 hours just to do a broken bolt back there. dropping the engine and getting it all done right takes a weekend.
The alternator is verry easy, take it out the pass side wheel well. : )
