[ERA174]

I've searched the previous posts and still need some advise on the best way to register my ERA Cobra in New Jersey. I have a PA title signed over to me from the previous owner, which lists the vehicle as a 1987 Replicar. I have not yet verified the engine casting number but it is a 428cj which should have a 1960's casting number. From reviewing the previous posts it looks like I will have to register it with collector status and be limited to 6K miles every two years. My question is, does anyone have any advise/experience with applying for a standard registration? Is there a process if I apply for a regular registration as a 1987 Replicar/Special Construction vehicle and get the emissions test for a 1960's engine, which is what is in the vehicle? What is the likelyhood of an ERA built in 1987 passing the normal safety inspection as a 1987 vehicle? Am I barking up the wrong tree here? Is collector vehicle registration the only option.

Thanks for any advise you can provde this rookie.
