Jim, I know that pg 80 isn't for V8 applications. However, the plastic clip on pg 89 for V8's requires a larger dia. hole in the dash suppprt, whereas my dash doesn't have that large of a hole and a sheet metal screw (identical to the GND wire that attaches above this location) was present in this location when I bought the car. The clip, however, was broken but looks like the 6cyl clip shown on pg 80.
