yep i made up plates 1/8 thick drilled a hole in plug welded a pin in. center the axle then drill a hole were the spring center pin used U bolts and bolted the plate in under the spring . rear end spring you can flip the spring side to side if the center pins not center ??.i had a 57 rear end under mine tires were never center to the wheel opening so i made plates to sandwich under the spring to center up on a pin. same thing as drilling a new hole . the plate work better for me . i did not have to lift out the rear end .i made up all new stuff when i went ford 9 ladder bars and floated the springs so i have my springs moved under side of the rails so i can run a widder tire under it and moved the back wheels were i wanted them did the same thing to my gto lets you get a wider and taller tire under the back of the car
