Im going to take a few pictures of the charging system in a little bit and you all can tell me what I have.

Usually a 12V coil will say something about internal resistance. I ran the12V Lo Boy a long time with a 6V coil (the old style) and the only time it was a problem was on real hot days. I have a 12V coil on it now.

That white piece is your 'ballast resistor'. The coil is the 'old style' I mentioned. So in that regard you should be all set.

Yup to what Larry said. Ballast resistors were common on Chrysler products in the 60's and are the ones most commonly seen when using a 6v coil with a 12v conversion. I would leave that original coil as it is. If you decide to return it to the original 6v all you will have to do is remove the alternator, remove the ballast resistor and change over the bulbs to 1133's instead of 1144's.

I just changed my oil pan gasket the other day but that doesn't seem to have been my problem. I think it's my crankcase breather drips oil on the side of the motor and then runs down onto the oil pan. Is that normal?

Just to make sure, check the resistance on the new bulbs to make sure they measure around 1 ohm.
You can also use some wire and connect them across the leads of your battery (polarity doesn't matter).
If you can get them to light, you probably have a grounding problem from the lamp housing (where the bulb gets it's ground) to the ground terminal on the battery...check the resistance from the lamp housing to the ground terminal on the battery.
