  If you are open to considering either a C5 or C7 IEC

 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.
