skinny o2 sensor

I bought a stock sr turbo elbow, and the o2 sensor bung is really skinny. Anyone know where I can get a skinny o2 sensor for cheap? since I’m sure my stock ka24de o2 sensor is not gonna fit. I am turboing my ka24de so I am using the ka24de ecu obviously, am I able to use the sr20det skinny o2 sensor on this? If not I’ll just rig my aem wideband to provide the ecu with the signal. So does anyone know the size of plug I would need to plug it or where I can get a skinny o2 sensor and whether it will work with my ka24de.
