Where to get (new?) power cords for vintage sets?

[compu_85]

Among the things which need attention on my RCA are the power cord... cracked insulation, and a prior repair attempt with the end of a lamp cord twisted on and taped over. Amazing someone would try to use something like this everyday

I carefully drilled out the rivets holding it to the back cover and am using it as a cheater cord for now. Where does one get a serviceable power cord these days? Rob one off a junk set?

Thanks!
