Went by Home depot...got Grade 8 bolts 3/8 X 4"...those seem like they will work well for the rear bags. Going to make some square washers to space them up on the trailing arms and spread out the load. Have some drops of thick steel I will use.
Tonight I simply mocked up the rear airbags, have a template made for drilling out the fitting for the bags, did some touchups on the frame, did a third coat on the control arms to give them more of a hammered texture, and mounted the power steering gearbox. I'm very happy with the silver next to the black. The black is almost a dark charcoal grey and looks great!!!
PS Gearbox mounted up
The frame as it sits
