Seat mounting bolt size

Anyone out there know the size of the seat mounting bolts (bolt to cab)? Mine seem to have not made it back from the bodyshop when the fleetside got repainted.

Re: Seat mounting bolt size

The bolts are 5/16-18 x 1". If you go with 5/16-18 x 1 1/2" it is usually easier to start them.
