Leaf Spring Bolt and Nut Specs

I have been looking and can not find an answer anywhere: what are the specs of the leaf spring bolt and nut? Specifically for a 5-lug second gen if there is a difference... I have looked at Toyota parts websites and can not find a part number or even a part listed.

 

uhh big? lol. it's the same size as the 6 lug tho if that helps

 

thanks kelson. well knowing that should help, that way if anyone knows they hopefully will post.

 

thanks 08 but i can not find the specs for the bolt and nut itself, but i did find the torque specs. is there something that i am missing?

 

my leaf spring eye bolt i bought one from local hardware store ,i got allen head bolt 3/8x2.5 fine thread. i torque it to 37 lbs then the u bolt should be 87 lbs with blue loctite for added safety. i hope this help.

 

That's what I needed to know. Thanks for the info.
