Hi Bob,
I'll defer to the advice of true experts like W8UT, but my suggestion is
to instead get a pair of "flush oblique cutters" and snip off the lead
to the old capacitor close to the connection point and attach the new
one to it. No connection with this seller or brand - but mine looks
like this: *http://tinyurl.com/5gpw5n *This cutter really helps get
in the tight spots and remove the old components.

*I've decided that even a careful workman can cause inadvertent damage
while unsoldering delicate connection points (such as on switches and
coils). I think the SP-600 RF deck especially warrants this approach.
To connect the new caps, Al Klase offers an elegant solution for a tool
you can make that mimics the old Sprague "quig" -

I often just go with a pair of interlocked loops or hooks for mechanical
support, followed by soldering of course. The appearance may not be
pleasing to some, but it's almost guaranteed to cause no harm.
