Here's a pic. Not even sure what I bought it for. But I'm thinking truck.
Here's Addco's instructions for a 951 sway bar. Do these look like your instructions?:

One of mine is blue too. But has a much more gentle curve around the rear diff and the curve not on the eyelet side of it.
What is the eyelet to eyelet distance of yours??
Mine is 35" It's seems like pn 919 is the one for A/B/E bodies.
