Others will have different opinions but I would clip the old capacitor 
or resistor leads leaving enough old lead to form a small loop for 
attaching the modern cap or resistor. When done I would have the new 
cap/resistor as close to the original location as possible with no 
excess lead. I would not risk breaking tube or IF can lugs trying to 
unwrap the original leads.

Ceramics are okay replacements for almost everything except little micas 
that probably can left in service.
