Here is another option, BB Mopar to Muncie bellhousing. You would want to verify the pattern that they have on the dyno but I would assume that Muncie would be one of the choices.

You can also redrill your existing bellhousing and/or weld a plate on it with the correct pattern. All depends on which way works out the easiest for you.
