You got off light- the damage will be limited to a distributor thrust washer, cap and rotor, probably an oil pump and a shim kit
to set the distributor height/gear mesh.
The labor is another thing.
You might want to go ahead and get shims
to set the distributor end play. Shims linked are for a 1/2" shaft diameter, check yours to see what it is before ordering.
The relationship of the dist. gear to the cam gear causes the dist. shaft to rise upwards
- so when checking the pattern, be sure the shaft is fully up w/all clearance removed from the gear end- that is how the dist. shaft and gear is when the engine is running.
I do not believe you could have broken the tangs off an OEM thrust washer like that- the OEM piece is thick enough that I believe it would have taken out the aluminum housing first. But in any event, that dist. shaft had to have been really bound up to do what it did.
