Battery chamber cover for a Mamiya 7 - replacement needed

I was talking to someone today who went to ready his Mamiya 7 for a trip and discovered that the cover for the battery chamber was nowhere to be found.
He is hoping that his three year old didn't somehow acquire it.
Any hints as to where he might find a replacement? He is in Canada. KEH wasn't able to help, now was Horst Wenzel. eBay doesn't seem to yield anything for him either.
He had to compromise and take the 4x5 instead!

Mike's Camera has listed some Mamiya spare parts - maybe it's worth a call ...

Thanks for that listing.
It is confusing, because unless you cycle through the photo illustrations, you don't see the Mamiya 7 one.
But when you do, it clearly is what he was looking for.
I've passed it on.
APUg is amazing, isn't it!

That ebay seller has tons of mamiya spare parts - bought a focussing knob for a Mamiya C3 a few years ago.
