68 318 Front Cover p/n 2946797

Needing front cover 2946797 for 68 Charger 318. This has timing mark on the passenger side. Prefer to find something close so I can eyeball it before buying.

As an alternative, can anyone tell me what would have to be done in order to use the later timing cover 2951698? Is it as simple as just using the later crank pulley?
