I have a s13 blacktop in my car, I'm not sure if when I got the motor it didn't have one or if I lost it somehow but I don't have the banjo bolt for my power steering. I have searched and found that most people get their ka ones to work for them, however I have 4 banjo bolts that I have found laying around my project area and none of them work. 2 of them are ka and the other 2 could be CA or RB. My question is where can I get a bolt that actually fits? All of the ones I try are to small. Id love any help possible, thank you.

I've been looking for the same part, let me know if you find out where to get one from.

Most parts and performance shops sell them. Just try to measure the length and thread pitch

I went to a few shops today and everyone just says the only place to get them is a junk yard. But how am i supposed to know which ones work? Does anyone know if the sentra bolt might work?

Get a standard metric bolt, like M8x1.25, M10x1.25 until you find the pitch.
