These came in the trunk of a car I bought awhile ago. They look the same but one is stamped s204 and the other s205. Did a search and nothing came up. Thanks.

tow or tie down hooks?

They do appear to be left and right, by looking at the upright sections.
Other than that I haven't a clue.

I was thinking engine lift bracket just now and searched google images and found this...

Mystery solved GM 3.8 engine lift bracket , thanks all.

Ohh crap! I don't know how to edit that long link to work. I cut and pasted it here but take my word thats what they are,

Thanks , delete everything after the "?" Appreciate the lesson too.

Now that we know you play with GM stuff, you get to stand in the corner, lol

LMAO! No, no,,,, these were in the trunk of a mopar! I can say though that the 3.8 Buick motor has always been my favorite in the 2000's My wife had an Olds Cutlass and a Grand Prix with the Buick 3.8 and it was Very dependable and great on gas. Had plenty of pick up and go for a daily driver!

i bought a bunch of kent-moore tools, new in the packages, at a swap,cheap, just to get a bracket looking piece i thought i could use for a project. it turns out, they are all gm speciality tools. how many corners do i hafta stand in, and how many suppers do i miss going to bed without for doing what i have done ? and by the way, that bracket looking thingy wouldn't work after all.
