I recently bought lower control arms, relocation brackets and panhard bar at Summit Racing for my car. The parts were on there clearance rack. They were display items previously.
The parts were all taped together and I got them for $100. Packaged with them was a set of upper control arms. I told the sales guy they didn't belong with the rest of the parts so he gave me a discount and said to keep them anyway.
I wonder if anyone here can help me identify what they are for so I can sell them. Here are some pics.

 

Looks like rear upper control arms for a Mustang.

 

That's what I was thinking. Notice one is longer than the other by about an inch. Is that true with the Mustangs?

 

I can tell you those are not 79-04 or 05-pres. Mustang upper control arms. They are to long. It looks like you have one arm from an Impala and another arm from something else. Good Luck.
