Drag link ends, tie rod ends, spindle bolts and bushings, shackle kits, spring eye bushings, toe in set, caster shims, and the steering box sent off to Lare's in Minnestota and you can pull the throttle out and read the sunday paper while it cruises in a perfectly straight line. First thing is to have someone that knows what they're doing (like a shop that works on semi tractors which still have straight axles) to see what is worn out and what isn't. Remember dragsters are running 330mph with a straight axle so they WILL track straight.
