Used to do a lot of kingpins years ago on mercs/sherpas.same principal.looked into tools myself.the only supplier I found was euro tools (mobile dealer like snapon)Great looking bit of kit but as i recall several hundreds of pounds and u still had to have/buy the hydralic pump.found it cheaper to zip off the u clamps and press out/in with hydralic bench press and refit with new u bolts/clamps.Dont know if u have a euro tools dealer your way,may be the price has come down,wouldent bet on it though,tool was german made imported and not a stock item.try mercedes comercial dealer,they probably still list tool for old 208/308.carry a big wad of cash.big.wad.Just thought ,company called churchill/vi churchill or varient(cant remember spelling) might be a good bet.
