Oh, yeah. That bracket, more like a strap. Mine was kind of a b!tch to line up with the dash frame holes. I had to to pry things together with a large screwdriver. Body bolts like this would have helped.

Au-ve-co part number 11320.

Buy mine from Rock Auto for .32 cents each & come in a box of 25 pcs. GM used this exact bolt ALL over the 67-72 trucks.

I don't know about those, but some are black phosphate coated to prevent rust. Others are not. Something to consider when using them on fenders, etc.

I don't remember seeing any 5/16"1-18 body fasteners that were not black phosphate but never say never. ;)

From what I have found, AUVECO was the original supplier to GM on these fasteners "back in the day" and the new ones I've bought from Rock Auto appear to be the same exact black phosphate bolts with a swaged-on washer that I've pulled out of literally dozens of original 67-72 trucks.
