I drilled them through and ground the flat. They mostly were gone when I was done. FYI, 350 lb rate spring is the lightest recommended rate. It will give you somewhat of a soft ride. 400 is the middle of the road. 450 will give a firm ride. I think QA1 recommends a 400 on most tri fives. A Nomad is a little heavier than a sedan too.
I put the spanner at the bottom when installing them too. It makes for an easier install. You can tighten them up after the install with the spanner wrenches. You might look into the spanner nut thrust bearings and throw away the washers. It is night and day when it is time to turn the spanner nuts.
