Short O2 Sensor

[JT88K5]

Does anybody know how I can find an O2 sensor for my 87K5 that is not six freakin inches long? I picked up a Bosch at advanced and it looked too long in the image on their site. When I picked it up I thought it was awfully long. From the nut to the outside end was close to 4” long. Stuck it up there as soon as I got home and no way it’s gonna work.

Been to several sites and Advance has a Walker O2 sensor that looks close to factory.
Stock manifolds are on it.

Would appreciate any suggestions on a part source.

Let me check and see what I have. I sold my 350 TBI and I don't need the 02 sensor. If it suits your needs you can have it for the shipping.

I think it's the heated 02. But let me check.

The O2 sensor that I have is a 3 wire heated sensor. If you want it you can have it for shipping. If not, it goes to the next in line that wants it. I have no use for it and it will sit on the shelf until gone.

It's 9" to the 3-way connector.

I found that part, almost identical to the Bosch part I had in hand. I don’t see enough clearance to install it. Mine is still the single wire setup. Last night I ended up ordering ac delco AFS20 on eBay. Supposed to be a new, still in bag part. Looks closer to the original in length. I recall reading something about the newer ( and longer) AFS21 being better in that it reads the rate of change faster.

Going to attempt to remove the old one in a bit. I’ll post a pic of the clearance.

Here’s a look. After removing the other half of the sensor, mehbe I could use the longer

What is right above your oil filter?

Sometimes there is an oil pressure sending unit on that port.

nswtfii except in the way. And after lookin closer ( at the picture), it appears to be leaking coolant?? I will check that out closer when I get the o2 sensor. Snowed six inches last night. Just about gone now. No hurry to crawl under her till things warm up a bit.
