As I recall, Florida had passed a law in '68 requiring ALL models (Ford, GM, etc) to have bumper guards. Of course these were obviously not necessarily San Jose cars. To me the production changes & dates, compounded by assembly plant variations make this a very ambiguous point. (Front AND Rear, Front OR Rear, total delete). I put them on every car, Front AND Rear simply because I think the car looks better with them. The safety factor (if any) is minimal. Under the circumstances of yes/no/maybe, I think MCA should be very liberal in their judging requirements on this point.
