Oil Fill Cap Question

[bjwestby]

I was wondering if anyone could tell me what color the original oil fill cap would be for a 1973 Dodge Charger SE with a 400 engine(P code Charger)? I bought an original F / E cap but it had been repainted orange. I have been told conflicting colors by a few so I thought I would ask.
Thanks
