12:05 Garage- ’70 Duster build

I did not use them (oval track springs). I used a set of 23K miles OEM 5 leaf springs, dis-assembled and redrilled the centering pin on the top / longest leaf 1" further forward, the second 1/2" further forward....and left the other three as is. Re-assembled and installed. It put the tire in the opening right where it needed to be. On the Flash, the springs only hold it up and keep the rear centered, the ladder bars do all the work.
