3955291AB BB Single Groove Crank Pulley

[69L78]

Has anyone ever seen one of these with a single groove, I did a search and on the Chevelle forum, someone made a comment they never made a single groove 291AB.

I don't think it was made as anything other than a 2-groove, otherwise it would be a different number.

I had one where the outer groove had been removed using a lathe. I never would have known it wasn't original if the previous owner hadn't mentioned it.

I suspect that is what happened to the one pictured in this thread.
