78 Dodge Chassis

[aliendude]

I guess my RV is a '78 even though the titile says '75.    The VIn comes up as a '78.  At both the insurance place, and at the smog station -- before I got thrown out for a fuel leak.  

So.....I know my windshield stick does not say CATALYST on it.....so it's a not catalytic converter one still - correct?  

Just the smog pump, EGR, OSAC dist vacuum delay, and heated air intake?

But my Stereo facia faceplate has illuminate light plug sockets for EGR and CATALYST.....  but there are no lights........

What does a '78 Dodge have....?
