Quick "which coil" question

[Farace]

I was supposed to bring my Spider down to the body shop this morning. Of course, it picked today not to start. I managed to figure out that my coil has gone south. I found an old coil in my box of spare used parts, installed it, and the car started right up.

Of course, I don't want to rely on a coil of unknown reliability. I'm hoping to get another coil before I head down to the body shop (tomorrow morning now), and I don't know what to ask for in the parts store (I'm sure they'll roll their eyes and say that a '71 Alfa is not in their books). I'm guessing it's a fairly generic part, but if there are differences, I don't know what they are. Can anyone tell me quickly? If worse comes to worst, I'll just leave the old questionable coil in there for now and wait until I'm sure of what I'm getting before replacing it.

FWIW, the car has its stock ignition system.

Thanks!

Stock ignition setup had an external ballast resistor in that era, so if nothing else, you want to avoid one with an internal resistor.

Beyond that, likely you can get away with anything from el cheapo generic to an Accel super yellow.

Darren, thanks. I've never found a ballast resistor in the car, and there isn't one on the wiring diagram. One wire goes directly to the points in the distributor, the other into a wiring harness and off in the direction of the ignition switch. The failed coil is a yellow Accel Super Stock, for whatever that's worth (and right now this one isn't worth anything). I see that both IAP and Centerline sell the Bosch Blue, and I've got to drive right by a foreign parts store on my way to work, so maybe I'll stop and see if they've got one.
