73' B3 340 Duster pro touring build

Congradulations on your success in restoring a cool car. My name is AC and my wife's name is Candy. We have your sister car, same color and all but a 1972, 318, small bolt pattern. Please contact me at [email protected] if you are interested in selling any parts off your suspension, rear end, front brake parts, etc. I am having a hard time finding parts in Ohio. Question, what is your bolt pattern on your axles?
