I tried to get an ohm reading off of the ignition coil and it was very inconsistent/hard to get a reading. The prongs look to have quite a bit of corrosion and the connector doesn’t look that great either.

 

Rear cylinder is not getting spark. Replaced plug wires and the front will spark (kind of weak) and the rear will not spark at all

 

I'm more inclined to think that judging by the picture you posted of the coil connection, that that's your problem. I just looked at it on my computer and not my phone and yeah I don't see how you can get a good connection there... That looks Horrible..
