Avalon65, I made them by myself...
The AC plug is the common 5266 (same number in different brands, in fact it is a code I guess) I always use Hubbell, well the other day I used a Leviton but I prefer Hubbell.
For the IEC one, being in USA I recommend you go directly to Schurter's website in USA:
you can even buy online, it is a nice connector from this Swiss company. The model I used in the picture is the 4781.0100 (10mm diamter cable receptacle).
It has a nice connection but lately, I am using some from a small company in Europe, these ones look more simple, maybe "cheaper" but the contact I think is much better, tighter the company in Germany is called BIA, I do not know if they manufacture them but the ones I bought were ok, and it's web site is this one (oldy'n ugly n'messy but it helps):
