Has Anyone Seen This Type of Cab Top Latching Motor Gearing?

[seafood10]

I apparently have a couple of Unicorn Cab top latching motors for my 88 930. I bought the URO rebuilt kit and then went to rebuild the motors but after cracking the gear case I saw that my internals are different and cannot find any info about them.

Rather than have a microswitch to stop the motor when locking and unlocking mine use a carbon strip on the gear and there are 2 pickup points as you can see in the attached pics.

When compared to the standard URO rebuild gear you can see mine has a collar on the shaft, it's stripped now which is why I was rebuilding them.

I know many people convert their electric top to manual and I may consider that later but I would like to have it working for the time being.

I sure would appreciate if anyone can shed some light on these gears, were these motors/gear case interchangeable with BMW or another car?

Thanks for reading!
