About all you can do is put a new banana plug on the end of the lead.
Life becomes exciting in a hurry when you have the probe on a 240 V,
30 A circuit and the plug falls out of the meter and starts swinging
around. Most electronics suppliers stock suitable banana plugs. Pomona
(see below) is a well-known manufacturer and has drawings for most of
their parts, so you can compare them to the ones that you have to find
one that will likely fit. The part search on Pomona's site kind of
sucks, though... it's easier to use the search at Digi-Key or Mouser,
and then if they don't have a link to the drawing, go back to Pomona's
site to find it.
Is it possible to get a pair of test leads that would fit either
meter?
It should be.
Do you have a preference for a supplier of these leads?
Pomona has nice test leads, and lots of nifty clips and grabbers and
things that work with them. Rat Shock has a couple of sets that you can
at least look at before you buy. A local electronics distributor may
have a few sets that you can look at, but the prices may or may not be
reasonable.
Just be sure to get the banana plugs that don't have the safety shroud
around the plug... they won't fit your meters.
This. Most lead sets have these now. You can *probably* cut off the
plastic shroud on the plugs and get it to work.
Note that you can go the other way: an unshrouded plug *will* fit most
newer meters and other equipment that expects a shrouded plug. It's not
as "safe", but you're sticking test probes into live equipment in the
first place...
Pomona still has a few lead sets that don't have the shroud: 5309A,
5325A, 5672A. $15 to $30 at Mouser and other suppliers.

If you want it today, Rat Shock has an $8 set (278-708) and a fancier
$19 set (278-038). You'll have to cut the shroud off of the plugs on
both of these; one reviewer of the cheap set says they did that and it
worked.

I bought the $8 set, or its predecessor, at Radio Shack several years
ago as a replacement for one of my handheld DMMs, and it works OK. It
didn't have all the safety approval markings actually on the leads, so
if you're using them where somebody will care about that, you might
want another set.
You can also buy probes that have banana jacks in the ends (Pomona
5689A, 6232A, 6479), and then make or buy test leads of whatever length
you want with banana plugs on each ead.
