Hello!

I recently bought some car "junk" - something that I had previously said I wouldn't do anymore - I had nearly vacated the entirety of my "extra" car parts;

I learned that money in one's wallet, and a (pre-1980's) "Firebird guy" with a garage stacked full and looking to get rid of stuff is a bad combination for me.
My wallet is empty, and I am scratching my head just a little bit .. lol

Some stuff I bought without researching what it was, on the off chance it might be good for me... the upside is I didn't pay too terribly much for the parts I bought "on the off chance" that they might be good for me.

I bought four jacks;
The two pictured in the attached image are of unknown origin.

I was wondering if anyone here might be able to identify them based on their shape at the coupler(?).
