Can get a new distributor vacuum advance module?
I have them if needed NORS, NOS or rebuilt. Where to set the initial is in the FSM for a start if it is worked. Here is the issue with parts store distributors, they are made well usually, just the curve is set up for a large span of years and applications, not any specific car. So it might run great or not but will make it run at a minimum. When greasing the shaft and advance weight pivots oil only. Synthetic grease on the rest. Also ensure the shaft oil seal is in the housing around the shaft bushing.
