Help Identifying K-members

Hi Guys,
I need some help identifying some k-members. I got these from an estate sale. The black one with the power steering came out of the dart pictured. I believe it had a 340 or 360 but not positive. The other was just laying in the yard. I also have 2 sets of spindles and control arms. Full disclosure I am not a molar guy I deal with classic chevy trucks but I love all classic cars and I couldn't let this stuff go to the crusher so I hauled it all back to my shop. Thanks for your all's help.
