Converting old amp to IEC power receptacle?

I have an older NAD 906 power amplifier that has an attached power cord. The built-in shelving which I want to put the system has a bunch of the previous owner's IEC cords already run behind the wall, etc. To use one of these, how difficult would it be to install an IEC receptacle in the NAD unit? I gather that since the original power cord was not grounded, that I should leave the ground tab of the IEC receptacle disconnected? Many thanks for any tips.

Here's an inline socket - you can attach it to the cord and not have to change the chassis. - shorten the cord for better performance.

I used a dremel to cut the hole when I installed an IEC in my Harman Kardon amp. A little bit of filing to clean it up and in it went. This amp also had a two conductor power cable so I left the ground unattached.
I also rewired the the AC cable from the IEC with higher gauge wire. Probably a two hour job.

Did it! I ordered one where they had the cutout template online, so I just used a drill bit and a Dremel I used a big vacuum cleaner to hopefully suck up the metal shavings as they were created. Then I blew the whole thing clean with compressed air. So, by the time the receptacle arrived in the UPS, it was all ready to go. There's still a length of thin 18-gauge wire inside the amp, but it's just between the power board and the IEC receptacle. There's no ground on my amp, so I just left the center plug of the IEC empty.

Way to go!
Replacing the 18 gauge inside the amp is way simpler than swapping out the receptacle. Might as well go all the way.
