Need some assistance ID'ing these old jacks.

Some old timer dropped off a couple old bumper jacks and said he had no clue what they came off of. Anybody recognize either one of these?

 

GM stamped the detachable hook with the car they were used for, really look over the hook on the one for anything stamped on it.

 

Thanks Squablow. The bottom one is from a 65 chevy. Still looking to ID the top one in the pic.

 

The top jack looks like a early 7o's Gneric Motas jack . scrubba
