4 speed aluminum Overdrive for A body

I have a friend who was trying to convert a truck (B&E body style twin shift plate) OD transmission to go into a 72 Dart. I told him it would probably be easier to find the 73-76 A body 4 speed aluminum OD transmission. He already has the bellhousing for the larger bearing retainer. If you have an A body aluminum 4 speed OD trans that you can deliver to Carlisle (I don't want to ship), please tell me the condition and how much you want for it and I'll relay the info to him.
Thanks in advance!
