Triple tree bolt size

[Ecwil]

I am putting together my front end after getting it powder coated and I have lost the four bolts that compress the triple trees and hold the fork tubes from sliding around.  I hope I can get the bolts from a local big box but do not know what size.  I could bring the trees up and find the bolts at the store but I did not notice they were missing until after I have greased them up and installed the lower. Does any one know the bolt sizes for 1981 CB750K or a place I can order a set.  Thanks for the help

Ah so the bolt size and thread pitch.  The shop manual didn't list this. I went to bikebandit.com and used their online fiche. Looks like size should be 10x35 so I would stop by a real hardware store and see what they have.
