dropping a datsun

my question is about a datsun 520 i believe i have aquired this truck real good shape and i want to lower it. I know it's torsion up front and last night i got under it to drop the torsions down and i realized that the bumpstops are only about and inch away from hitting at stock height and i can't seem to feel or see a bolt holding them on. Any info on how to lower this would be great.thanks Ryan

I know on my 521 the bump stop is welded on So I will just have to cut them off. I am going to put mine on the ground by flipping the kingpins and crank on the t-bars some more! I dont know the 520 is setup in the front or I would have some more info. Hit up layed521 he should know on the 520.....
