WTB: '70 Challenger, non-A/C heater box

[Jeffs 1970 RT]

Hello,  Looking for a heater box for a 1970 Challenger.  I do want a nice one that I can rebuild (ie no broken, missing pieces) OR, if you have one already rebuilt, ready to go, that would work too!  Located in IN, would be willing to travel to pick one up.  Let me know!   Thanks,  Jeff
