@ Dave - Thank you for the correct terminology!! We see what you guys are saying now, like it should have been flipped. Makes sense because I feel like the parts were worn oddly, and I think that the tumbler-looking piece looks like it's been modified.

@ Harold - I will definitely send you a message! I would be interested in purchasing a correct mast jack (😊).

@ Joe - Thank you for the information, and the link! Hubby and I were able to visualize what you guys were talking about and it was indeed flipped! Thank you for the info on the grease, too!

This is what I'm curious about - The first piece I'm holding looks worn oddly, to me. Or is that just how they're made? There's only a small portion without the lip/groove. The second tumbler-looking piece - Original condition or modified?
