Replace the whole thing, looking at the damage.. the rack most likely skipped a bunch of teeth, youll have more turning radius one way. Racks are very weak, ive had customers wreck there rack from hitting a curb in a parking lot, there not ment to take much.
Buy it used, ive came across some that where 150 bucks for the whole assembly, including inner tie rods.
I hit the grass/sand on the track, doing 100+ mph, My rack skipped like 8 teeth.. i found a used one out of texas, 150 bucks + 80 bucks shipping.
