As others have said Phil the best materials are Hardchrome Kingpins with spiral grooved (for grease dispersal) bronze bushes, you will need new top bolts and best fit new upper grease nipples as the MMC used more than one thread form so you know everything fits. One issue is your close to the date when adjustable camber plates were fitted, these can be seen as a threaded stud welded to a plate and locknut at the bottom of the kingpin (if you send a photo I can tell you) these cars have dome topped kingpins and concave lower faces to the top lugs. It's further complicated by the fact I have seen cars with dome top kingpins fitted to flat plate top lugs and flat top kingpins fitted to concave top lugs......both are incorrect. Sounds complicated but really isn't you just have to ensure whoever is doing the work has both types of pins in stock. As Forest Gump said you never know what you've got. ;-).
