I am reusing the rear leafs off an 87 4runner. I want to replace the rear bushing (shackle end) with an actual bushing with a metal sleeve and not just the stock rubber with a huge 3/4" hole for the shackle. The diameter of the rear eyelet is approx 1.2", the front of the spring is larger at approx 1.6" so they are not interchangeable. Lots of folks have used these springs so i figure i would check what everyone is using. If you have any ideas or have seen something for sale please let me know.
