I've been working on the ignition system for my 1972 240z, which lately seems like a disaster.   I've been working on replacing the old coil and there is a small condenser attached to the positive terminal on the coil  with a single wire.  It's screwed down to the bracket that holds the coil.  I bought a replacement pertronix 1.5 Ohm Coil with ballast resistor, but can't find any sort of condenser for the coil anywhere.  I've read a lot on the forums about whether or not this coil condenser is important, and opinions seem to be all over the place.  But assuming I want to replace it just to be safe, where can I get the condenser?  Or is it even needed with a newer model coil?

I run a 1.5 Cane fireball with my '79 zx distributor, no small "beer can" condensor. Plugs at .44.  Works great.
