Need Help. Shock Bolts.

[mdeal]

I just recently bought some rear shock relocation brackets for my 71 C10. But I didn't get the bolts with them. Does anyone know the size of the bolts I need? I can go to local bolt warehouse and get some good grade 8 bolts, I just need the under head length and thread size. I know (by looking at pictures) that there are 4 long and 4 short with lock washers and flat washers along with nuts. Looks like the long ones are bigger thread size too. Any help will be appreciated! Thanks!
