thanks for the replys. the jeep will be registered in a non-emissions county, it only has to pass the nc safety inspection. the reason i ask is that since i swapped the 304 and have the title from the '75, i might accidentally mix up the VIN numbers between '81 and '75... i guess to be on the safe side, i will find a catalytoc converter somewhere and tack it on for inspection in july. does the cat have to come before the muffler, or can i put it behind? thanks again! jairus
