2\" narrowed with welded in adjusters will give you the height you want, but 3\" narowed you have to modify the body slightly nothing odvious..
on a balljoint beam?? i could have sworn i heard someone somewhere going 3\"s and still clearing. the best way to find out would be to grab the old measureing stick.
and imho, it would be way better to modify the shock towers than hammer on the body.
andre...it sounds like you want the classic cal-look rake. 2\" or 3\" narrowed and adjustable beam, narrowed tie-rods, with your spindles, a set of caster shims, turn the torsion bars up an outside notch in the back, get some 135's or 145's for the front and some 205/70's for the back.
so...buy matts beam and sway bar, go to airspeed and get your narrowed tie-rods and caster shims and tires, and do this to the rear....
1. Take off the spring plate covers. (4) bolts on each one.
2. Undo the axle tube from the spring plates along with the lower shock bolts and let them hang (4) bolts per side,
3.disconnect the e brake cables.
4. pry the spring plates off the outer torsion bar splines and turn them up (I usually go 2 notches) then slide the springplates back on bolt it all back together and you're done.
You can do it from the inside splines or the outer but make sure you do both sides the same.
but it also depends on how you want the car to look. do you like big & little tires? do you like the look of a rake? are you running stock wheels or something else?
good luck and be sure to ask for help if you're stuck. it works for me.
