Default Front rotor bolts

Anyone know of a black rotor bolt for the front rotors on a twin cam? Harley's stock # is 3655a. Lyndall makes 2 types. A low profile for $100 which seems a bit much. Or the arp 12 point for $30 but I'm not sure if they would be too tall and hit the forks. Google search comes up with an M5x10. Not sure if that's correct or not.

ARP makes top-quality hardware.

EDIT: If you read the description on Lyndall's website: "ARP Bolt kits are also available for sprockets, pulleys, and rotors (these will not fit rotors on a 39mm/narrow glide front end, as the 12 point head is too tall and will hit the forks.)"

Perfect. The drag specialties is out of stock so I'll probably order this.

Well we don't have to guess here, if you have a 39mm front end they will not fit.

I always thought the head was a little bit smaller on the drag specialties. I went back to the stock bolts because it seemed to Center the rotor better. The head of bolt matched the inset hole on rotor. If ya know what I mean.
