Sourcing Specific Connector Contacts (For Original 203W Xbox 360 PSU)

[BAM5]

Hi there,

I've got a project where I'm building a custom PC and I've decided to power it with an old 203W xbox 360 PSU.
Instead of chopping off the proprietary connector at the end of the PSU I've opted to make a more polished look by disassembling a xbox 360 to slim xbox 360 power connector converter..

Taking it apart I see that there are only 4 out of 6 power carrying contacts on the plug and I'd like to be able to add the 2 more, but I'm not sure where I can get these contacts.

I've tried googling all sorts of terms but just find the standard terminal / blade crimp connectors. I found a site called TE Connectivity and manually searched through their power connector contacts catalog but couldn't find anything that looked like what I need.

What is your process for finding parts like this? And if you don't mind, could you help me find these??

Here are what the connector and contacts look like.

And here are some dimensions pulled from the contacts.
Height: 3mm
Width: 3mm (Not including stopper tabs)
Length: 18mm (From end to end)

Thanks for any help you can provide!
