69 dart conv rear window regulator help?

help please. I have a 69 dart convertable thats almost finished.Thing is the rear window regulators.Are they the same as the two door hard tops?You would think yes right, but we have a pair out of a hardtop that just dont line up .Its like a different shape all together.Being a dodge I would not of guessed that it would be different due to expense, but they have a different window and stuffed if we can figure it out.Also its the only known genuine conv in Australia so there is nothing to compare to.Pics or advise will help and get her on the road.
