Installed the rear 4" drop springs with new clamp/retainers and hardware. Springs are from CPP and the clamp kit was from LMC. Bolted in EZPZ. Way easier to bolt in then it was to remove the stock springs and clamps.
Installed new upper and lower cross shafts up front. The lower shafts were a tad different, but after I started to install them it made sense. The seals are a bit different and improved over the stock shafts so they needed to machine a deeper shoulder on the shaft. Still bolted in and lined up just fine. You can see the difference in the pic.
I bought new 9/16" grade 8 lower control arm U-bolts from Summit Racing. They are actually for later model trucks but will work with my 1972 shafts. The holes through the crossmember and through the cradles of the 1969 frame are already large enough for the bolts no problem, so I didn't have to drill them out. The thick grade 8 washers did not come with the bolt kits. I sourced those locally (Ace Hardware) and they will have to have a tad bit of grinding done to them to line up correctly in the crossmember.
If anyone is interested, the U-bolts are made by Dorman and here is the Summit Racing part number:

Will install the front drop springs soon. Just gotta get new disc rotors and calipers and I can then bolt everything up front back together.
