Modifying k frame

Tomorrow is the day I am doing it! I still can not believe that no other gearheads have done this before. I guess I will be the test subject! We are going to bolt up the tranny first and take measurements off of my buddy's 340 Dart Sport. I will let you guys know how it goes. He is the redneck MacGyver so I hope we can figure it out. Wish me luck!
