There is a substitute for the kingpin bushing, but I recommend original Stude ones, the Studes are Steel-Backed, and will take the pounding. The new replacement is an oil-lite bushing and may not hold up as well in a daily driver. I don't have any long-term data on this. I do not have the oil-lite number for this reason- Dave Thiebeault (978) 897-3158 should be able to give it to you, or provide the bushings. 6.Outer CA Bushings- upper and lower- Stude only. 7.Upper Inner CA Bushings- use Moog K5196 (GM & CHEAP!)for the upper inners- MAKE SURE YOU USE THE SPREADER/SPACER TOOL! when you install these as per shop manual! 8.Lower inner CA Bushings- no substitute.Stude only. ======================== A-Arm Bushings - TRW - Lower 12202 - Upper 12244 MOOG - lower K-3045 - Upper K-3044
