Need help finding TM G18C parts

[TacticalBeard]

So last game I played with my TM G18C the rear sight screw fell off without me noticing and I lost several parts in the next few shots (the selector's pin and spring, the selector base cover, the selector spring and the sight screw).

The part numbers are the following: 18C-5, 18C-6, 18C-7, 18C-19, 18C-22, 18C-23.

I can not seem to find a shop that carries these online (or at least most of the parts). I have looked at firesupport which have nothing in stock, tokyo model which has only the base and the selector but it doesn't have the little spring for the selector, Eagle6 with almost everything but its all out of stock, etc. I also looked at buying the Gk tactical selector base cover and spring, but I'm unsure of the fitment with TM guns.

If someone could help me sourcing these parts or finding an alternative such as a slide set to upgrade at the same time, this would be golden. Thanks for your help guys!
