Correct Bumper bolts

[stickman]

Im installing my front and rear bumpers on my 56. When i purchased the car it was all in boxes so i need to know whats the proper Bolt size to use for bumper installation.

Thanks

Bumper to brackets? Brackets to frame? Which size I can measure mine as they are sitting on horses right now.

I would need bolt size from brackets to frame..i already have bumpers assembled and brackets on them as well.
