1976 FJ40 with about a 4 inch lift (guessing, not sure how you tell). PO added this modification to the rear shock mounts at the top of the shock. Why would you do this? Should I attempt to cut it off and salvage the post and run a die over the threads? Do they make a shock that could accomodate the way it is now without trying to change it? Current Rancho shocks look like they have been on there for 20 years. Any and all advice appreciated.
