Just purchased TCI front springs from ORD for my SAS in my '90 3/4 ton. The main spring eye takes a 9/16 bolt, and the shackle eye takes a 7/16 bolt. The 7/16 bolt is the part that concerns me. Is there an issue with having this small of a bolt in the shackle, or is there an upgraded bushing and sleeve that I could purchase to get this to 9/16. My Jeep used 1/2" bolts stock, and now it has 9/16. Thanks.
