DSRTRDR- I tried a few of my scsi covers and video connector plastic pieces and they are close but not an exact fit. Grab a few connector covers and try them out on your wiper. I did a quick measurement and they are 2 7/32" x 1/2". Not having the piece I would guess that could be anywhere from 3/8 to 1/2" high. Let me know how you make out.
Mark- Get some made and you could make millions! I think it would be less expensive to purchace an entire motor.
the largest cover I have is precisely 1/2" x 2" (inner dimensions of plastic), medium size is 1/2" x 1 11/16", and the shortest 1/2: x 1.5". But my truck is in AZ :-( and I am in NE; so cannot check until in a few weeks . I haven't started scouring the mega plastic places yet (can't believe there would not be a thingy in Walmart or Home Depot that couldn't be made to fit; the snapping function might be difficult to fab). Apparently the OEM piece gets lost too easily, justifying the need for an "aftermarket fix" I'll let you know when I find a good solution. In my truck, I first need to solder one of the wires onto the stop switch again, it's just hanging there. (The OEM soldering apparently leaves something to be desired, too, even though all is well protected behind the sun visor).
