As the title states, I am looking for a good replacement for the upper spring seats for the rear suspension. For the lower seat (coil to axle), I plan to just look for a spring sleeve. The Diameter of the springs is about 2.75-2.80" so I hope its not hard to find one. The upper however is just super cracked and coming apart. If anyone has any replacement ideas, (including using newer Nissan spring seats), let me know what you have run.
If you have ARB coils also let me know how they feel. I currently have Cheap Monroe Blue Body Shocks but plan to buy Bilstein 5100s or 4600s in the future.
