Does anyone know what size the front seat bolts are??

Somehow after the track day last weekend my two front seat bolts are missing :suicide I have another track day and Cornerspeed class this weekend figure I might need the seat bolted down.

any one find out the size of the front seat bolts? I too need a pair!

Mfg. Part Number: 09139-06065-XC0

I think its a 6mm bolt (thread, not head). Any bolt 6x20mm will work.
