Chris,
your just better off cleaning the floor off of all the auto console brackets, place the hump in location, it will position itself on the floor, an ideal situation would be to just mock up the bellhousing, tranny and shifter for an exact location...afterwards locate the console based on were the shifter is located, and weld your brackets where need be, if you mock up the bellhousing/tranny, nows a good time to locate the inner frame bracket for the Z bar, this way you can "fine tune" that location/geomerty exactly as needed....your stock auto tranny crossmember mount will be the same for your 4 spd
