If you are open to considering either a C5 or C7

instead of the C13, you'll probably have better luck with the PSU
vendors. If you don't need the ground/earth terminal (I can't see why
it would be needed for a replacement C64 PSU) a C7 will also cut the
per unit cost and allow for a smaller case.
I don't think you mean C5 (or C6). That's a 3-pin, the one sometimes
called "mickey mouse ears", and one of the less-common types. I mostly
see it on Toshiba laptop power supplies.
C7 (cord connector) and C8 (inlet) is 2-pin. It's the one often
referred to as "figure of eight", and the only common 2-pin.
No...I did mean C6 (3-pin) since Jim mentioned asking PSU builders about
the C13 (C14 inlet). If the PSU doesn't require an earth/ground terminal
though, the C8 would probably be a better choice since it would be less
expensive to implement than either a C14 or C6 inlet, and take up less
space. The only other reason I could see for using the C14 over the C8 or
C6 is that the C14 is good for up to 10A, whereas the C8 and C6 are rated
for 2.5A, but I really can't see a C64 PSU needing more than 2.5A at mains
voltage.
The C5/C6 is now very very common with newer laptops and IT equipment. In
the US, the C7P polarized version is extremely common with consumer home
audio equipment. Both the C1 and a coupler similar to the C1 that is more
rectangular with rounded corners (still 6.6mm c-c) vs the more oval
version in the standards are also very common with battery powered
portable radios and similar that also have an internal power supply. The
'rectangular C1' cords that I have on hand are made with 18 AWG SPT-1 cord
and have 125V 7A molded into the coupler body.
