Magnum with OEM EFI Throttle cable?

For those of you running the OEM throttle body on your magnum, what did you do for the throttle cable where it attaches to the pedal?

I've already changed over to a square hole in the firewall for the OEM magnum cable, but it has a funny setup on the end of it. It has a sleeved washer crimped on the end with a plastic thing under it, then about 3/4 " down it has a ball to keep it from going too far into the sheath.

See pic, The issue is that when the cable is connected to the throttle body, that little ball is right up against the plastic housing so I can't use that to clip into the pedal...
