replacing shackle bushings
I am replacing my rear shackle and leaf spring bushings in my 1986 CJ-7. I took evrything down and bought new grade 8 - 1/2" bolts. I am using Energy Suspension poly bushings and with the new bolt there is no room for the metal tube that goes between the bolt and the poly bushing. Is it necessary to use the metal tube that would go between the bushing and the bolt. The kit that I bought did not come with them and the bolts that I bought fit it perfectly.
