i recently blew my zc and bought a new one from a local shop and it was compleatly diffrent from mine it had a cam seal where the cam angle sensor went
a obd 1 dizzy and the intake manifold was compleatly diffrent as was the driver side motor mount but it definatly was a zc it also feels stronger than my last zc
could i have gotten a newer zc or a modified zc?

 

Yeah, there are OBDI ZC's I just sold one to my buddy.
