Transfer case oil change parts for 05 tundra?

What screw do I need for this? Toyota parts site says 90341-A0001 but seen videos of people using 90341-A0002.

Can I just use my old screws and get new seals - 90430-18008 appears to be the ones I need.

Thanks for any help, I am trying to start doing DIY on my truck.
