Dear Hans;

After you get the size/color you like, all that's needed is #6- 3/8" bolts & the 2-3" flat washers (street side) that the bolts fit through.

They are a MUST for them to stay mounted to the FLOOR in case of a collision etc.

FYI: A #6 bolt will have 4 'hash marks' on the head and should have fine (SAE) threads.

Good luck. \:\)
