Repairing stripped teeth on CD changer mechanism?

[fastpenguin]

Stopped off at a small thrift store last week to see what they had and picked up a Marantz CDC-6R 6 disc CD changer for $5.
It works fine except when trying to load/change CD's from the magazine it makes a bad grinding noise.
I replaced the belt, but the plastic teeth on the plate (whatever it's called) on the side of the changer driven by the gear are worn down/stripped at the beginning of the track (see pictures, sorry for newbie terminology)

I can't find much about this CD changer in the first place, let alone parts on eBay... I understand that this era (1988) Marantz was owned by Philips so I assume there's probably some crossover.

Are there ways to repair the teeth on this piece or do I need to find a replacement?
Does anyone know generally what models or brands might share this part in common?

This changer works with a remote (will buy once this problem is sorted out) which my current JVC does not, so I would like to try and get this thing working.

Thanks!

From what I can tell from the photos, this looks to be moulded as part of the entire tray assembly, which is quite common.

You might be able to remove it and replace with a stock linear gear track.

Great! Linear gear track, that's a good start. If I can't find a direct replacement, I don't have much to lose trying to find one that matches and cut out the old teeth and glue in a replacement somehow.

Anyone know if this model has much in common/interchangable with other brands/models?
