Cluster Woes

Hi Folks I hope everyone is well as they can be ?
Could I ask for some assistance? I have recently bought a 73 Dodge Dart 318... apparently it was in Dark Shadows... Anyway it had a few owners and I'm working through all the faults. I had to buy a used cluster and due to the pain of taking the cluster out I thought I'd replace all the bulbs as most were busted and the headlight switch was busted. I found that even after changing the bulbs and testing the printed circuit the oil pressure light and the direction indicators don't work. I've replaced the oil switch as there is power going to it. Any thoughts ? Common issues ?
