alscrx

I have a factory b16 manifold in my 91 crx and everyone knows there are 2 oxygen sensors on it.
What sensors do i use since its obd0? I want something that will clip in and not universal. I know its a 1 wire!!

I know One of them uses the oem crx clip(white round plug)
The other one is square green plug which i know can't be found in the us. But was wondering if i can buy 2 of the same sensors and just depin one and repin it in the square green plug??

What application should i get them for??
