I would have felt a little better if there were some drain holes in the frame. If you know enough to mod it the way it is you should know enough to drill a few drain holes. Especially in a rust belt vehicle.
Hang in there. You'll find another one.
Where are you in NJ? If you're north enough to be able to make a trip to Long Island I have a friend who buys and sells TJ of all different flavors. Might be worth a conversation with him.
