Johnny, just fitted hard chrome king pins on my 4/4 and Plus 4. Hard chrome is different, more industrial, than show chrome. Supposedly will last my life time. We will see.
Jay is very much correct in that the link I provided was for an older car, and it shows damper blades instead of the bearing 'thingees' that replaced the damper blades. Most of the cars we have in the US are still old enough to have damper blades. All of mine do.
I have been to both the north and south islands and envy you the great, scenic drives. Met up with Morgan folks on the north island in Paraparaumu, as well as Wellington. Enjoy your road trip!!
Cheers,
