Help Identify this Crank Pulley

[goonfan]

I have a single grove for a 280z, don't want to buy another single groove (want this done today) so I need a factory solution. The old pulley worked but I don't know what it came off of, that's the pulley I need help identifying.

 

 

Here's the pulley I have now. It's garbage or I would just get those bolts out.

 

 

 

See those 2 bolts sheared off in those bosses? I need those bosses, I can't fire my dizzy without them if I can't mount my drive gear.

I can't find a single example of this. Most 280z/zx had so many accessories they we all dual or triple pulley. The 240/260 had some single but I can't find any with those two bosses.... which begs the question what were they for? originally if not for the crank fire ignition?

Dale Manufacturing rebuilds them better than new.

That's what I'm starting to think too, not finding a stock option at the JY today. I pulled my 280zx dizzy off of my series one (still have the points of course) as a back up plan just in case. I think I'm stuck looking for a single groove, kinda sucks because they are not cheap.

 

 

Thanks for the link, I'll keep it mind for the future but nobody is rebuilding this.

Possibly for a 240z with a/c add on. Not sure what mine looks like.

Did you try an older Chevy?  The reason I say this is the speedi-sleeve for the front timing cover for Datsun L/Z series is the exact same for Chevy 350s, etc.  I haven't investigated it myself, but I've heard of stranger things.
