Hi Jon, have made a start on the front suspension and finished the steering rack mods today. I need to take a trip to my local MG spares shop tomorrow as I test fitted my new uprights today and tried the new castle nut but for some reason it didn't fit (seems to be incorrect thread) thought I must be going mad so grabbed the old one from my old uprights and that didn't fit either. The only thing I can think is for some reason the new uprights have a different thread pitch but who knows!!!!
