I could really use some help right about now.

The pickup mount will just bolt in the same place as the stock mount. It is just thicker, and has the tabs to keep it from pulling completely apart. I used to sell Anchor mounts at the parts store I worked at, and they are garbage. Don't plan on it staying together long. Also, if the original mount is worn a bunch, and that's what's causing the "sag", going to a pickup mount may lift it more than you want. If you have the correct brackets, with the mounts installed correctly, you should not need to lift the engine. Of course, the headers could also be for the incorrect application, or just crappy headers.
