front suspension rebuild.....

[hewlett2002000]

ok so as some of you know im putting my truck together. i need some help with a front end kit. my truck has disc brakes from a newer model truck on it but i dont know exactly what year. when i bought brakes for it i said 72 and those worked. if i get a complete front end rebuild kit from lmc for a 66 will everything fit? or do i need one for a 72 or a mix of the two years? also the kit from lmc for the 66 says it comes with a sway bar bushing set, but my truck does not have a sway bar. is that just in case it is needed?
the kit from lmc comes with....

1 polyurethane sway bar bushing set
2 upper ball joints
2 lower ball joints
2 upper a-arm rubber bumpers
2 lower a-arm rubber bumpers
2 outer tie rod ends

$149.95


ill add inner tie rod ends because i need them. $19.95 a piece. i also need the adjuster sleeves. $8.95 a piece. they have two adjuster sleeves listed, one has ps beside of it, i assume this means power steering. i dont have power steering now but i will in the near future. will i need to get the ps ones?

i appreciate any help yall can give me.
thanks,
John
