Another method that works well is to use individual adapter
boards for each cap. The boards are roughly the same diameter
as the original caps and allow a modern snap cap to be used.
You can make the patterns up in any drawing program if you want
to etch your own, gerbers are floating around the web and
they are available on ebay once in a while. The boards work
out to be around $1 or less each if you use one of the cheap board
houses.
If you use long leads on those, you can thread the cap in without
having to disassemble the scope.
That method seems to have been independently invented four or five
times that I'm aware of (and probably many more).

Subject: [TekScopes] Replacing Electrolytics in a 465/465B
Recently, I had a problem with the LV supplies in my 465B. Thinking it was a
shorted electrolytic can, I decided to replace all of them (although it
turned out to be a shorted tantalum but had already pulled the cans before
finding the real problem).
I decided to design a small PC board on which to mount modern snap-in caps.
THe board mounts with standoffs in the exising larger holes that are left
when the cans are removed and allow replacement of the snap-ins if/when they
fail and that can be done without further soldering on the original board.
Pictures of the board and the process are in the following album:
