Bed Bolt replacenment
 

I'm reassembling a 1996 F150 basket case I bought.
It didn't come with any of the bolts for the bed. I'm going to use regular grade 8 bolts instead of actual bed bolts.
Anyone know offhand the different length bolts needed?

4, 4” bolts and 2 3” bolts I do believe.
While I do appreciate overkill grade 2 bolts will work just fine.

Thank you.
