I have seen the front coils cut on several of these trucks, (always with a cutoff wheel too, 68 c-10) my family has been doing it for years, The truck may bottom out a little easier but it has never affected the ride quality on any of them, I cut a full coil (circle) out of my 3/4 ton it dropped it 1-1.5 at the bottom of the front bumper, I then installed standard 1/2 ton shocks and it rides like a champ.
Now if the spring is shot its shot, cutting a coil out will make it even softer, which may be what Big Al is referring to.

I would try cutting the one you have first and if it works great, if not buy yourself a set of lowered ones and try them
but what do I know, I'm just a low life pink named user.....
