Take a look at the pivot points first, a general run of thumb is the top ball joint and bottom ball joint, draw a line between pivots and the ball of the tie rod should fall in this line. The inner pivots should be the same, then try to get the tie rod linkage level with the control arm it close to. The lemght of the tie rod assembly should be at the two lines, GM generaly has there point match the lower control arm, take a look under a S10.
You should also look at you old spindel arm height, as bump is more tied to a differance in arc pivot heights.
Try the arm as is but with some washer on fitted to the taper of the rod end to raise the pivot and check for bump, if the bump decreases thats the way you move it(the washers are for bump test only)
