OEM Frame Aux Battery Box- Bolts?

[desertspeed]

I just picked up an OEM battery box to add a second battery on my frame from eBay, but it didn't come with any mounting bolts.

Yes, I know I can just use some grade 8 bolts/nuts or fabricate something up, but I was wondering what the stock mounting bolts are like- I can't find any pictures online.

I was hoping it was something like the trans cross member bolts, like this, so you don't have to try to hold the bolt while tightening:



Does anyone have any pictures of how they mount? Thanks

OK after looking around some more it looks like these are the mounting bolts:



So I guess the question is are there captured nuts mounted on the frame (mine does not have any) like these?

That's what they look like on my 97 E350. Both the 'nuts' and bolts.

Same here. Captured nuts. 2000 E350

On my e350 theres a plate that the capture nuts are attached to.
