Gears and axles

Im not tryin to sell anything, it has whatever the stock rear end that came in in the dart with the slant 6, prob a 7 1/4. It has drum brakes on the front, 73's are supposed to have disc but mine doesnt. I will sell the stock rear end whenever i get the gears and axles for the new housing i have. Looking for big bolt pattern for if i get the front swapped to disc brakes but will take what i can get for now
