1998 Vortec 305 negative battery terminal to engine ground

[Tech-GeeK1500]

Just a quick question, had my main ground off on my truck the other day and dropped the stud that the main battery negative/ground wire attaches to and can't find it anywhere. I've been scouring the internet for info but for the life of me I can't figure out what size and thread this bolt was to replace. Does anyone by chance know what to replace it with? This is the bolt that is in the same area of where a mechanical pump would sit, right around the corner and about an inch or two away. Thank you for any assistance!

Well, a fuel pump bolt is 3/8-16, takes a 1/2 wrench. Maybe try that?

Found what I was looking for at the junkyard, was slightly bigger than a fuel pump bolt. Thanks for the idea though.

Junkyards are so educational, eh? BTW, I would not be surprised if the bolt you needed was metric, as it seems almost all the bolts and nuts on my truck are now metric.
