64 rear torque specs

[heel97]

I am replacing most of the rear suspension on my 64 short bed and am looking for any info I can find on the torque specs for when putting the parts back on. I also needed to know if anyone has idea of proper torque for replacing the shock mount crossmember rivets with bolts. Have the bolts and set to bolt new crossmember in but not sure what torque range I should look for to make sure it holds as expected. Thanks for more help.
