90 or 91 BAP sensor

Hey guys, I posted this already a few days ago but I'm not sure what has happened on here????? Missing a bunch of posts.

Anyway, I have a chrome bap sensor cover for a 90 or 91. I have an 87 and have a map sensor. My map sensor is acting like a bap sensor as I have switched my car to mass air. The chrome cover will not fit over my map sensor as it is much larger than the smaller bap sensor.

If anyone with a 90 or 91 has a picture of their bap sensor and/or a part number for me, I'd like to see what it looks like and get a part number.

If anyone could help me out, I'd appreciate it.
