Milodon gear drive timing set on 410 stroker

I went with the gear drive timing set instead of a chain. I had 1/4" taken off the fuel pump eccentric like the directions said. Otherwise it rubbed on the timing chain cover. The problem is when the gear is slid on the cam there is nothing to stop the FP eccentric from turning. The only thing holding the eccentric is the cam bolt. The key on the cam does not stick out to catch the slot in the eccentric. I also had to grind about 1/4" off the head of the cam bolt too. Anyone using one of these gear drives and how did you make this work ? Pictures ? Milodon #13600
