um yea i have double that in lift, 9" is real easy
springs are about $400
ubolts about $40
77.5-79 ford d60 about 1k
oru kit for just spring hangers is $700, i recommend just using stock gm brackets (front spring hanger from 73-87 4wd chevy and rear spring shackle hanger and shackle from a 73-87 2wd flipped upside down) as far far cheaper
drag link and track bar varies greatly by what you use, i have threaded dom and stock 73-87 drag link ends for the crossover steering and used dom with weld in bungs and heim joints for the trac bar($120) which you will definitely need with 9" lift and crossover steering.
shocks all the way around are about another $100
add in the cost of driveshaft, my 94 i had 10" lift and used a stock front shaft from a 84 gmc 1/2 ton that had a sm465/208 in it with the 4 bolt flange, just had to grind the stops in the double cardan a little, with a dana 60 you need to make sure the shaft has a matching 1330 series joint.
next there is the rear, if you plan on any towing it makes a difference in what to do back there, you will want a 10.5 rear for sure but how you lift it is where things change for towing
