what size grade 8 bolts are you guys using in your 2wd conversions?

I recently acquired '69 bare shell of a blazer. No top, no interior, no motor or tranny. All it jas is the 4wd axles which im yanking out and swapping in all 2wd 5lug gear. My questions is what grade 8 bolts are you guys using to bolt in the crossmember?

I used 3/8 grade 8 bolts.... couple of sources if you don't have a good local hardware store. (Mcmaster Carr) has all sorts of hardware and fuel hoses. Have you got measurements for crossmember placement? Post some photos
