I am looking for a timing belt cover for my 1990 B18a1. I took the motor to a shop today to get it timed for my nitrous and they said I was missing the arrows things to show how many degrees advance or retard you go. They said I still have that white center line but they said I would need to get the rest of it before they could time it for me....so if anyone has what I am in need of let me know I have cash in hand.

P.S. I am pretty sure it is part of the timing belt cover but if someone knows something I don't or knows exactly what the piece is called I am looking for please inform me. Thanks
