Just came across this thread. I have a stage1 Isuzu, the RH Railco bush is stuffed. I must have got the last genuine stage 1 Railco bush in captivity from my local Land Rover Indy. He said it has been in stock for a few years. I also note that all 4x four manufacture them or have them manufactured as they said they have them in stock and are available as a kit, tho a bit exxy. Cheers
