Dart Sport shifter questions

Ok thanks guys for the help. I have a 75 Dart Sport with a column shifter. The car originally started out as a 6cyl. car. Not sure what trans. The problem I am having is with the shift linkage. Where te linkage bolts to frame and comes straight across to trans will not lay straight. It has a small bracket with a plastic bushing that bolts to trans that the rod lays in. I have flipped it up or down it makes no difference. I cant get enough throw on the linkage to achieve low 1. It hits the bell housing. Is there an aftermarket cable system besides a floor mounted shifter that I can use with my column shifter? Maybe The car had a 904 before. My car has a 727 now. Any advise would be great.
