Let me thank you all in advance for your patience... but I probably deserve a little heat for this mess up.

About- a year or so ago I was digging around in an unrelated project when I saw that my stock negative battery to ground cable was crusty and disgusting. You can see in the first of the following two pictures how bad it was.

I spent a heck of a time finding a direct fit replacement which Amazon shipped to me and... it was not a direct fit. It was several feet too long. I had another black cable that was the right gauge to go between battery and block.

I have no idea why I went with battery to block and not battery to frame but not having another way to get it done, I buttoned up the battery to block connection and called it a day.

Since then I have put about 1,500 miles (I don't drive much) on the truck and aside from a short lived climate control issue, and a short lived window motor issue (both resolved themselves for no reason I can determine) I have had no real issues with the truck.

I finally got off my butt, and went back to Amazon, and found a new "direct fit" cable and since I had the old cable to match to and the two appeared to match I ordered it up. Again, what Amazon sent was not a fit. So I grabbed some 4 gauge, some terminals, and using my very nice anvil set up, made a new cable that would tie block to frame (you can also see this in the first picture).

Today I went to do the install. Man my memory ain't perfect but, I remember a stud sticking up out the frame that the frame side of the cable connected to, and I do not remember removing the stud, only the bolt that kept the cable on there.

I'm 99.9% sure though that that nice hole you see in the center of the first picture, which is threaded, is where that stud was, though. I cannot find any studs on the frame, or any other holes, especially none that "fit". That hole also vaguely lines up with what looks like either brake or cooler lines to tie them off to too.

I have an appointment next week to get an amp and subwoofers installed on my truck. I've got my fingers crossed that someone can point met to the correct size of bolt to jam into that threaded hole, and I'm thinking I can just jam a bolt in there and call it a day. Or someone can reinforce my delusion and tell me that it's all going to be ok, that ground wasn't super important anyway.

Can anyone help me out?
