New AC/Delco Alternator
In case anyone is interested, I purchased this new AC/Delco 335-1040 Professional 105 amp alternator from Amazon for $76.81 ($73.50 plus tax), plus I got free one-day shipping (I'm a prime member). The website photo shows gold fan and pulley; the one I received had a black fan and gold pulley. It is now showing $88.54, so the price has increase since I purchased on 7/1/18. Seems to be working fine so far.

Re: New AC/Delco Alternator
What is the rating on the factory alternator vs. the one you installed?

I think that they are both 105 amp, but not sure.
