I did not use the deep nuts. I think that's where I went wrong. I just looked at a picture of the replacement nuts and I now recall that the originals were deep nuts. There is no torque specification that I can find for these nuts (1956). Manual just says secure firmly. The centering bolts on both leaf springs are lined up with their holes. Don't know if I used grade 8 washers or not. Also, I think these U-bolts are probably not fine thread.
