I had to do my alternator three times

, dumb autozone, and the exhaust manifolds twice, I cracked one buy hitting my driveway. I still can't get one bolt back into my rear exhaust manifold. I checked for leaks, none for now at least. Waiting for it to get above freezing. Being 6'4" and 295, I have huge hands and the gymnastics that you have to do to get at the rear exhaust manifolds is incredible. When muscles get in the way, not that I have any, that's insane. I did all of this on jack stands, no fun. Concrete is cold in the winter.
