General Bolt Size Master List

[Jacksonrobinson]

Hey everyone, I'm restoring my 1980 C10 and wanted to know the best way to determine the size of any bolt. I want to replace many bolts, but I don't have the original bolt to reference. I have a service manual but am having difficulty finding specific bolt sizes. Is there a master list or other resource to search and find specific bolt sizes that are used?

I hope my question makes sense.

LMC stocks most of the bolts for things on this truck. They unfortunately don't say what the sizing is in their listings. The fasteners tend to be the same across much of the truck though. The same bolts are used to put the entire front end together just about. I picked up a couple bags of LMCs fender hardware and put lots together with just those.

Do you have a specific area you are focused on?
