FM Towns Marty 2 cd drive sensor rubber belt

hi guys. i bought a fm towns marty 2 recently from ebay. the seller tested everything and it was ok according to the listing.
once it arrives to me, the cd drive was not working. i opened it up and a small rubber piece fell out.
i slowly diagnose and found out the rubber piece was the connector between the sensor and the cd door.
i had to use cellotape to tape the sensor and cd games are working.
is there anyway to get a replacement rubber connector or something similar?
thanks.
