my nut and bolt dilemma

[Puglia10]

I figured I'd get more responses in here than my build thread so here goes. I bought a 1980 completely disassembled (another kids burnt out project) so my problem is I don't have half of the hardware to bring in to match with new grade 8. I'm trying to put my control arms, cross member, (well, the WHOLE truck) back together, so what should I do? Are there packages/kits? Is there a reference guide for all the hardware? I'm lost, thanks!
