318 vs 360 mounts?

If you go to the "Magnum swap" section and look at my thread. "My 5.9 into 68 Dart swap". Scroll through till you find the part about how I modified my drivers side 318 mount to work on the 5.9 (360). It might give you some ideas. You can buy a 360 mount if you can find one, or buy the aftermarket swap brackets, but its much cheaper to modify your existing mount.
