Whoever had this truck before me disassembled it put all the bolts in a bucket and grabbed whatever fit when putting them back.

I'm trying to figure out what the proper hardware for these mounts is. I think I have the right size bolt I just need to know what it gets..

Bolt with 2 washers and a lock nut??

Mine are a 3/8" bolt. Not sure of the length. There's 3 and they go in the slotted holes. I believe my bolts are factory and have a flanged head with flanged nuts. It's pretty tight in there so you might have to use a bolt with a washer under the locknut.

I think you might be talking about the clamshell holders to the mount pictured. I'm talking about the mount pictured to the frame.. I believe its a 7/16 bolt but not sure if I should use a lock nut.. lock nut & washer.. lock washer & regular nut.. Does it matter.. am I overthinking again (I tend to do that)

When I removed mine(just put back two weeks ago) the bolts had washers but no lock washers
