I know it avail at many parts outlets.. but have heard it needs to be modified for our application

I see one on Jerry's website, which looks OEM.. However, He lists only 1991-995.. what about 1990?

is it a different sensor?

No PM from you Hans,

Right the replacement, according to Marc, needs to be adjusted to fit..

I was curious on the specific part Jerry has

Here is info I received from Marc:

Quote:

I use the Standard Motor Products sensor. Number PC7. It has a metal bracket that must be removed and cut down to about the size of a dime to allow the sensor to seat. The sensor is about .030" smaller in diameter. I use a larger o-ring to be sure that the sensor does not
leak oil. Then I wrap the sensor with aluminum tape to increase the diameter by .030".

Just a typo Jeff. In the body of the full description, it correctly states 90~95. Thanks for calling it to my attention.

Replaced it today.. 5 min job. My sensor had a metal spacer and I also found oil had leaked in the electrical side due to cracks in the sensor

I have attached a couple of pictures

The VIN for your 1990 must be under 0500. I hope you left the shim in place. It has to do with DIS Module which is also unique to the first 500 of the 1990 model. After that, the DIS Module was modified & the shim was no longer needed.
