Do you plan on doing the work yourself or have a shop do it?
Front end rebuild kit: 4 tie rods, lower ball joints, upper ball joints, lower control arm bushings, strut rod bushings, upper control arm bushings
New Idler arm
1" Torsion bars
Hellwig 1 1/8 front sway bar (has good attachment hardware)
I'd hold off on the leaf springs.
Do you have disk brakes up front?
Are you rims large bolt pattern or small pattern?
