I have these sitting around, should probably go to someone local, What are they worth? Notice the Y has a broken ear on the end, other than that they're clean...

 

Do you have the ear? If so, and it can be welded on, it may be worth about $25, and $50 for the good one. If it can't be fixed, I say worth nothing, Years ago I had some , asked $200 for the nice set, got $150. Had bad ones, had to give away, or scrap.

 

I don't have the piece that was broken off, these were on my car, no leak from that broken ear. There was a large washer under the bolt head. I'll see what I can get locally.

 

They are available in reproductions, so broken parts are kinda worthless to a restorer.
