ok first of all, HOW crucial is it to have the upper and lower bars parallel.. i know i need to be as close as possible.. but, could it be a few degrees off or would that be really bad?

then if the answer to that is they have to be perfect.. since im running all 4 bars off 1 crossmember.. tell me if this shit below even makes sense at all, or if itd work to measure the lengths of the bars..or if i wasted my time..lol

1. set the truck at ride height2. measure 2.75" from the bottom center of axle and mark it on a block of wood thats also sitting on the ground.3. nail broomstick to that point.4. center the point back under the axle.5. swing the broomstick up at the other end to the center of the framerail and nail it to a block of wood.6. measure from point to point. (THATS LENGTH OF LOWER 4LINK BARS)7. using a level, measure the distance between the point on the block under the axle, to a point thats about 3" off the side of differential. (Thats the exact distance the front 2 mounting points should be apart)8. Whatever that distance is, subtract 2" because the crossmember is 2".9. Divide that answer by 2 to know the length of the upper and lower tabs coming off the crossmember.10. Add that TAB LENGTH to the mounting point of the front of the lower bar. (THIS HEIGHT WOULD BE THE BOTTOM OF THE 2x2 CROSSMEMBER)11. Using a level, cut 2 blocks of wood that sit on the driveway that match up to the bottom of the 2x2 crossmember.12. Lay a piece of 2x2 steel across those 2 pieces of wood, check for level again.13. From the top of the 2x2 Crossmember, hold the tape off of it the TAB MEASUREMENT from before, and measure back to the exact same differential mounting point as before. (THIS IS MEASUREMENT OF TOP BARS)
