R9237-9079 Square couplers

Has any one bought part # R9237-9079 from the Fisher-Price parts store?
If so do the hooks have the larger or smaller sized mounting hole?

What do they look like?

Thanks chrisjo but the reason I didn't direct link is because it gives an error if you haven't already entered the site from this link:

Here's the image with most of the white cropped out (which doesn't show the hole size, should have posted this earlier):

They're the coupler type used on Harvey's coach and motorized tenders.
If no one has an answer I'll probably just buy a couple sets anyway and find out for myself.

I am not aware of these having anything but the normal sized holes. These are great to have on hand and of course can change the battery box Cars and coaches to a normal hook in front coupling on back set up.

Well, I feel like bit of an idiot....
The car I was trying to convert (a loose tinplate C53 tender) has a larger than normal front post.
So the car is odd not the couplers I have.
I'm still pretty sure I DID take a hook with a larger hole off a junk tender a couple weeks ago but can't find it at the moment.
Thanks all.

How much bigger could it be. I would think you could ream out the hole of those hooks unless the post is very much bigger. If you find it come back and show us please.

Will do so if I find it.
Probably will just ream out a regular one for the tender.

this seller's offering definitely fit on trackmasters. Ebay seller Totally Thomas should have them too.

Disassembled a Splish, Splash, Splosh! Emily tender and found it has the larger hole hook coupler so here's a photo comparison:

Turns out it's still not quite big enough for the C53 tender so reaming a larger hole it is.
