Oil pump drive question after a distributor less conversion

if I was running EFI or independent coil to plug I would probably need that cam sensor. At this point I just need to be able to plug the hole and run the oil pump

Really the only two choices are the cam sensor and AndyF’s (ar engineering) plug. Both are around ~60 bucks. You don’t have to use the sensor. The cam sensor from a later model jeep can be had from the junkyard for cheap.
