The distributor drive gear is cast into the cam, so no repairing it.
The engine will have to come out and be turned upside down. The lifters come out the bottom, no way to hold them up to get the cam out. You'll want to replace the lifters, so the pan will have to come off. If the old cam looks good, and the lifters look good, you "might" get by without new lifters, but taking a big gamble. A used cam and it's matching, in order lifters will also work.
While in there, take a look at the cam and crank gears, PS gear if equipped, and the governor parts. If you do have the pan off, and I recommend you do, take the oil pump screen off and clean it, take the oil pump apart and clean and inspect it. There will be pieces of the cam gear floating around, best catch them while you can.
Also replace the distributor gear, take the distributor apart and inspect it closely. This is not a common failure, the distributor could have had a problem causing the gear to fail, or the gear failure could have damaged the distributor. Don't want to have an expensive second failure!

I guess I should have stated this before I rebuilt this engine last year so I just had the entire motor apart. Oil pan has been off did the head and new rings and pistons everything looks good on the cam so I did not replace it I also just rebuilt the distributor

The replacement cam needs to be reground as it WILL be worn with lit and duration off spec. Doesn't cost very much to true up a cam and resurface the followers.
Measure the valve spring pressure too. Every now and again a spring will go soft.

It has new springs, valves, valve guides,
and seals. Also pistons and rings, crank
bearings, carb, etc.... basically a full
overhaul. The only thing I didn't do was the
dad blame cam shaft
new governor and rods
but not the cam.

I would still look the distributor over very carefully! Something caused this, maybe the cam gear got chipped, but I would want to know exactly what happened so as not to have a repeat, very unusual for that gear to fail.

If I recall correctly from working at the MF dealer years ago there's a difference in cams an distributor gears between the Z-134 and Z-145. Believe the cams will interchange but the distributor gears are different, nine tooth on Z-134, ten tooth on Z-145. Match parts carefully..
