Rear quarter window motor

I read somewhere (way back when, maybe here) that there was a replacement Bosch motor that would work with some modification. Does anyone remember this?

What year is your XJ-S or XJS convertible?

I have a 1990 and a 1991. Both have 1/4 window problems.

I don’t think my pictures were copied over from the old site. Hopefully this helps?
