8 1/4 large wheel pattern 2.76 diff A Body

Thank you for the enlightenment, yes, The driveline is different. I had a couple nice offers but I have not fooled with cars in many years and costs have really gone up. My Dart is a 4 door driver only, (nice one too) I have a pride and joy Duster that all my money is reserved for right now. so I'll rebuild the 7 1/4 if I can't locate an affordable 8 1/4. Thank you everyone for your help. Didn't mean to write a long mopar blues story (LOL)
