Like said above, good luck with that Vinny! I have been in search of one since I bought my Hemi Dart with no luck. I do know where there is one in your town of Macomb, MI but I haven't been able to get him to sell it to me...
Last one offered to me about 2 years ago was on here and the guy wanted 150.00, which he did sell. Mine was a case of no heater box so I had to come up with a substitution.
