7 1/4 OEM spider gears help

Hello themoparman73. After much discussion with several knowledgeable friends I have decided to drive the Dart to it's new home in Montana with the existing gears, and then change out the 7 1/4 for something with a little more beef. I am planning on the gears being able to make it 1,000 miles! If a major failure occurs a friend will come and get me with his trailer. SO, I respectfully decline your offer of a 7 1/4 diff. Thank you for your offer. jejhnsn
