New starter

Has anyone put a new starter on an early Dart without any drama? The one I bought was for an early 90's Dakota. Both wires coming off the starter relay are too short to reach the new terminals, and the black wires connector won't even fit over the new starters stud if it was long enough. Most of the others I'm looking at appear to have the terminals to far away from my relay to reach them. What am I missing? Thanks!
