63 dart cable shift tranny

stabbed a slant back in the dart along with a LONG tailshaft cable shift 904. must of come out of A100? for what I can tell. long story short, It would work but the tranny mount bracket will be right where the speedo cable hole is. it will also require me fabing a bracket to front side of crossmember bracket which I could do. I can keep it for parts or sell to someone needing one for A100 (good luck me!). so i'm looking for an A body slant pushbutton tranny.........
or if anyone has any other ideas???????
