I was right the hole was too small to fit the socket from the top so I enlarged the hole about 1/32" and was able to get it in. But now the issue is that the chassis thickness makes in darn near impossible to fit the retaining washer in place. So now I'll have the enlarge the hole a bit more so I can fit it from the bottom with the mounting bracket underneath. Removed the other 42 socket too so I won't have an arcing problem from the other socket.

Hey Ron tell Deb that I just finished the last brown sugar/cinnamon cookies , they stood the test time! Found a few after digging though some of the stuff that I came back with.

 Are you sure that the wavy retaining ring won't work? Some of those are a bit tricky to get on, you have to sort of feed the ring into the groove, spread the ring, and push down at the same time, with some small flat bladed screwdrivers. One problem that you may run into is that the hole in the chassis has no key to stop the socket from spinning, so what I did was use some Permatex glass and windshield adhesive around the bottom of the socket flange. 
 In my case the socket holes were too small as well, but rather then making the chassis hole smaller I mounted each socket in a Unimat lathe and made them slightly smaller by maybe .020'', I figured that it was because they were Soviet/Russian made octal sockets manufactured in Metric rather then U.S made Amphenol ones. Bakelite is a lot easier to grind down then steel plate.

Well I was thinking in my simplistic mind that it would easy just to snap those rings in and be done with it be but on this thing you need to be an octopus with a hand full of pliers and small screwdrivers. And wouldn't ya know it my lathe is on summer vacation!
The other socket is mounted under the wire wound bias resistor. If I remove it the bracket is kinda in the way still.
Yes there isn't a keyway I was going to just use a heavy gauge piece of wire soldered to the heater ground terminal and fasten it to the chassis.
The dremmel makes pretty quick work of enlarging the hole. Takes 10 minutes or so. Seems easier to do this than fooling with the groove in the socket and try to get the clip in place.
Then back to the osc problem.
