[72BLAZERDUDE]

I got front cups from Suicide Doors and they dont seem to sit all the way down in the spring pockets on my 72. Has anybody else had this problem. It looks like i need to grind a taper on the bottom to fit down flat since the spring pocket is tapered. Also am I supposed to bolt the lower conrtol arm to the bottom of the bag through the cup or bolt the cup to the bag and allow the trucks weight to keep the cup in the spring pocket.
