Project`67 Dart GT 340 A500

Hmm. You are inspiring me to do this... I currently have an A999 trans in my duster. Been thinking about OD for awhile. I have access to tools that will help me rebuild one.
I converted my A999 to non-lockup a while ago. My thought on lockups is I always had a concern about those hollow input shafts and the lack of TQ converter options.
