[V6-12v] CATS for OBD1

I replaced the driver side cat on my '94 100 a couple years back with one
from www.discountconverter.com.  Mine is an OBD I car but, the cat was
good for OBD II cars, as well. (I believe the '95 100s are OBD II.) 
Anyway, the only difference was that the new one had a threaded hole on
one end for the scondary oxygen sensor.  Since it wasn't already capped, I
just screwed in an old OXS plug and I was good to go!
