You don't need a shield on RT510 - especially not a cooler - just a mechanical retainer.  Being hot is what makes it work; cooling reduces its operating range.

I wish to thank Rich for his posting here.  He has an item I would have 
bought after my parts post last week.  The only "list" I found in the 
great information on R-390A.net for tube shields said to use 6020B's, so 
that's what I was searching for and was glad to find that something else 
would work.  I STILL need what looks like 13 of the 5020B ones for all 
these 6BA6's and 6C4's if anyone has a stash of those.  The only one 
left in the rig I am working on was on the 3TF7!  The rest were all the 
shiny shields.
