id say you got it all covered, not bad for delco parts.
good time for sway bar bushings if you need em. the caps are in the clear with the sub frame dropped.
Shared album - Scott R - Google Photos frame dropped, rack pulled already. note how far i dropped the frame, bout 6 inches.
some tips. wheels dead straight lock the steering wheel, dont touch it or play with it.
pull the boot off the rack to expose the bolt in the shaft, remove that then pry it off, you can lower the frame 3 inches or so safely to make some room. get the old rack out, then lay the new and old side by side and get the steering nub there to match the old, makes getting the shaft back on easier to some degree.
take your new lock nuts, measure how far in the old lock nuts for the tie rods were, put the new nuts at the same measurement.
once its bolted back in lines are on, pull the shaft down as far as it will go, now jack up the frame till the shaft meets the rack nub, then go a inch more, now work that fuker on, having a helper move the steering wheel ever so slightly can help line it up.
afterwards hit the alignment shop, you'll be close but not perfect.
