Rear Wiper Motor interchangeable - 200 vs 300?

Hi all

Are the internal working mechanisms (particularly the motor itself) on a 200tdi rear wiper motor interchangeable with a later 300tdi? I've managed to clean up my 300tdi motor and get all the gear mechanism working smoothly again, but the brushes on the motor itself look pretty poor. There are loads of 200tdi ones on fleabay, but not many later 300tdi versions and I wondered if I could just swap out the motor.

Cheers anyone!

i have a fully working 300tdi 1 £10 collected pal

Thanks for the offer chap but I've surprised myself by managing to fix the old one this morning! Dismantled the whole thing again, cleaned up the brushes and greased everything - sorted!
