To be more specific I'm looking for the floor with reinforcement at the front just prior to frame rail. My car does not have the reinforcement stamping at the rear.
My assumption is the 3 versions are:
1. No stamping front or rear
2. Stamping front and not rear (what I have) - 2 cars confirmed one San Jose built 4.10.67 and one NJ built 4.11.67 both original floors
3. Stamping front and rear
