1992 240 ignition coil questions

I was cleaning up the contacts on my ignition coil when I managed to snap one of the towers open on the coil, and it looks like I'm in for a new coil. Fortunately, pick and pull is having a sale this weekend that puts the price of a used coil at 6$. I'm planning on bringing an ohmmeter to test coils, but I'm wondering what Volvos (or other ) shared the same coil type as my car.

As I understand, the 89-93 240s had the EZ-116K compatible Bosch coil. (Please correct me if I'm wrong) Is this coil shared with other cars, maybe the 740s and 940s of similar years?

When testing, I'm going to be looking for a primary coil resistance of .6 - 1 ohms, and a secondary coil resistance of 6.5 - 8.5K ohms. Is this correct, and is there anything else I should look out for?

I'm sorry for the many parted question, thanks in advance for any information you can provide.
 
Update: every one of the 240 coils tested bad at the yard, but I found one from a 740 with the correct resistances, slapped that in there and it's running very nicely. It's not quite the same size, so it won't screw down, but it sits in the holder and doesn't squirm around when I drive.
 
You can use a coil from a B234F 16v LH 2.4 car, it is a bit hotter spark but works well. You'll need to change the coil wire connector at the coil end though, as it has the pin style not a socket like the 240 coil
