bolts for pilot spacer
the hughes spacer is a press/tap fit into the rear of the crankshaft(can only be used with a curved flex plate(5.3,LS1))
the gm 6.0 spacer uses longer bolts and if you have the flat 6.0 flexplate the spacer goes on first then the flexplate then bolts,, if you use the curved flexplate the flexplate goes on first then the spacer then bolts
