Cut the nut off and weld it to the other side. Now you have to stick the bolt through the frame rail.. There is already a hole next to the hanger. Drill a larger hole in the inside of the rail so a washer plus the head of the bolt goes through.. You do not have to enlarge the hole next to the hanger. The bolt will pull it up against the frame rail . Pull the hanger against the rail tighten the front bolts. Now remove the large bolt. This allows the spring to be installed after the the hanger is in place. This can be done with any hanger just weld a nut on opposite of the rail and move the hanger against the rail by changing the 4 stud locations. The head of the spring attacment/ big bolt ends up inside the rail. You can use the original bolts and nuts.
I don't know if you all noticed . but this car has a full exhaust with tips before and after the mini tub. with factory tip hangers. Steve
