Bumper Bolt Thread
 

I'm an idiot, I'm putting a new bumper on my 95 150 and the factory bolts are shot. I need new bolts, so I took one with me when I left the shop last night and somewhere between my shop, home, bars, and work today I lost the bolt I took with me. I need to know what the thread is on the two threaded inserts on the frame. It's standard course thread I think it's 9/16-12 but it could be 5/8-11 anyone know so I can pick up new bolts on my way to my shop afterwork.

Thanks,

Pat
