I'm away from the truck, but the opportunity has come up to get a new bolt for my trac-bar.
Can anyone tell me what size and thread it is?.
I'm referring to the bar that is attached to the chassis on one end, and attached to the front axle on the other and runs parallel to the steering track rod. The truck is a 77 F150 4x4 and I need the sizing for the larger bolt on the axle end of the rod.

Thanks in advance
Elliott
