Capacitor wiring help

I bought a set of these capacitors on EBay recently, and received them today.

I'm assuming by the little black line on one end, that they have a positive and negative end, and that the black line denotes the negative. Is this correct?

If that's the case, then the other thing I need to know is how to wire them in to my Classic Series '50s Esquire, i.e. where to solder each end. I want to keep the wiring as is, but put these capacitors in place of the stock ones. Here's the stock diagram.

Or this one

Can anyone tell me how to proceed? Of course, I might be falsely assuming that they have a positive and negative end, in which case, disregard everything!

Thanks in advance.

 

Never mind, I worked it out from some pictures of the wiring of a '58 Esquire. Tricky, but it works.
