Kinkpins, what size? The kit I like is Napa 262-1016 for the GM 1.109" kingpin. This kit is most common and therefore cheap, also has thrust bearings not washer and steel backed bronze bushings, not plastic. It however does not have the freeze plugs as used in older spindles. If you need those look in the kingpin kit book at NAPA and look up the kit you need, several choices for the 1.109" kingpin. List all other kits by size too if you need something different.
Unfortunately I have not found a good price for individual bushings, better off buying a kit at Napa or eBay.
