Installed leaf springs & axle today, but questions

On a side, assuming his specs. are right, this is very nice: http://www.chuckschevytruckpages.com...que_specs.html

Edit: He's not specific about the rear suspension, c-10 vs other. That and the original U-bolts on my C10 were 1/2". They were replaced with 9/16". Looking at his specs of 150 FT. POUNDS, I can only assume he's referring to grade 8 9/16" U-bolts, but it strikes me 150 is too much for even that. I put 50 lbs. on. While there's more to take, it feels close.

This might be a better source. That said, I think I see why a lot of guys say to tighten until you know it's right as opposed someone's specified torque, too many variables: https://www.suspensionspecialists.co...nformation.pdf

Per a phone call with this group, the max. torque setting for 9/16" grade 8 U-bolts with the upper and lower plates is 100 ft. lbs. Their page reads 93 ft. lbs., but perhaps a decent range: https://www.autoandtrucksprings.com/...-u-bolt-torque
