I looked on rockauto for a front right (with RWD) and didn't see one, yet they offer a different part # for a '96 with 4WD/AWD for both the left and right front.

It might help if you pulled yours off so you can better compare it to the pictures of what they have. I looked for a picture of the Ford part # you listed but only found crude drawings which told me nothing about the differences.
I am wondering if the right side is a mirror image of the left side, if there is that difference or only a difference in the cable length. If it's only a cable length difference you may have to splice in more cable or get rid of slack if it's too long, OR is the cable detachable and you can reuse your old cable with a new sensor? Well even if the cable is not detachable, if it's in good shape you could splice on a new sensor, making sure the connection is waterproof.
I would check the cable connectors and test end to end continuity to confirm that the cable itself is intact before ordering anything, if you were to try to reuse it and only replace the sensor module on the end of it.
