Stuff leaking out of ignition box.

That leaking stuff is called potting. It is used to keep moisture out and also to "hold" components in from vibration. In your case any good OEM replacement box will work, whatch out for the new "fake" ones usually have mopar authorizedand no writing on the transistoe. There is a how to thread on how to spot them. Yes I have some if needed also. Hope this helped.
