thanks for posting the Jerry.
I'll be real curious to find out what the real deal is......
since what's quoted below doesn't make a lot of sense.

partly what doesn't make sense, as far as I know, is that a cat for a 1996
car, for example, isn't any different in how it works from a cat from a 1986
car ...........
the later cat might have a spot of a post-cat oxygen sensor .........
but the material used in the cat isn't different or anything like that, as
far as I know.....
it's the entire engine management system that's different in OBD-II compared
to OBD-I and pre-OBD cars.

what they are leaving out is the very very fine print ....the fine print
from Ca that says ( we, the State of California,  are trying to get all
older cars off the road in Ca. )
