Yes, that's the newer type aka Amphenol 160-2N (thanks for that part number) which would work fine for a "mid-70's or later" Fender amp. Also looks like a decent source for some parts. I used to shop at Apex when I lived in LA and they were on San Fernando Rd in the Valley.
It is my strong belief and recollection that those newer, grounded variety require a chassis hole (at least) 1/8" larger than the older, ungrounded 2-pin ones from older Fenders. That's whether mounted from the inside or the outside. The OP needs an older style 2-wire ungrounded type.
The point being, these things are pretty expensive (for what they are) and if the goal is to restore a broken receptacle on an older Fender amp...if these newer ones require enlarging the chassis hole on an old Bassman or Super or Twin, personally I would much prefer not to do that.
As I can't locate any source of the newer 160-2N 3-wire type that has a spec sheet that specifies hole size, I think we need to ask forum members to measure the black plastic header size on the old type and new type AC sockets, supply their results here, and compare. Should be possible from the outside of the chassis. I can't tell you what year it was, but the one time 25+ years ago I had to replace the accessory socket on an old Fender, I got the new type and it was too big for the existing hole. Back then, I probably reamed out the original hole and thought nothing of it.
Today, I wouldn't do that to a Fender that was old enough to have (only) the old 2-connector style. I would cover the hole with a blank plate, eliminate the socket, and be done with it. Obviously an individual choice.
The other choice (assuming you can't get older smaller style) would be to make a blank plate with a square hole in it for a genuine amp-based PITA piece of fabrication.
