Connection spares

Hi
I was wondering if anyone had a supplier that they get the following parts from:
I am looking for more tender pusher connections or for the second car motor vehicle.
Parts at the bottom of the picture.

I used have someone on eBay, but they disappeared a while back.
Can anyone help?
Many Thanks
AOF

here you go Search trackmaster fisheye hook, and you should find a lot sellers to choose from.  

The hooks are expensive.  Sadly, I scrapped some engines and rolling stocks for parts such as couplings to save money for more trains I don't have.

I can't remember where I got mine from as not too long ago I got a bunch of them so I could dye them. Maybe it was Amazon. I will check.

EDIT:
It must have been longer ago than I thought as I can't locate where I got them from. Maybe they have them at Amazon.jp

Yikes...I certainly don't remember paying anything near $20 for 3 pairs.
