     I rebuilt the front suspension on my 71 Midget and ran up against this 
     problem too.  The rebuild kit came with all the required components.  
     I had the kingpin bushes replaced and reamed to size by a shop which 
     has been an MG dealer since 1952 (yes, they only sell restored cars 
     these days) I wasn't about to add that expensive reamer to the 
     collection where it would see such limited use.
     
     At any rate, when picking up the parts, I queried the chief mechanic 
     there about the proper torque setting for that nut since it was 
     nowhere to be found in the Bentley manual.
     
     Hang on a second while I put on my flame proof undies...
     
     His directive was to tighten the nut until there was no vertical play 
     measurable in the spindle/top trunion, and the assembly could turn 
     freely lock to lock. Being uncomfortable with that response and 
     blessed with an instinct for survival, I called the Moss techies and 
     got the same instructive advice.  Further, they advised that if the 
     kingpin was cross-drilled for a castle nut, then assemble as tight as 
     you can while maintaining alignment for the split pin, yet not so 
     tight as to interfere with free movement of the assembly.
     
     I put a small punch mark on the kingpin and the nut (nyloc on mine) 
     for reference, and they have not moved.
     
     With this in mind, I'd advise you to back off the nut a bit.

Hey everybody,
     
Today the front suspension was supposed to go back on, but I have come 
across another glitch.
     
When I tighten the king pin nut down, the spindles will not turn.  After 
a few of us (it was during the tech session) scratched our heads, it was 
decided that the shim that sits between the kingpin and the spindle was 
not enough.  Dennis Bufton had a parts manual, and it show that there 
are three sizes that are available for this purpose, so we are probably 
on the right track.  The problem is that of the major suppliers, only 
Mini Mania lists these, and they tell me that it is basically on 
indefinite backorder (they may be able to find a couple out of a broken 
kit in their shop, but they won't know that till next week.  After I 
called Moss, they used the parts numbers I had and had 2 (of the .008), 
those I bought, but would rather have a little more to work with that 
just two, and I would like to get the smaller size (.003) so I can get 
this right.  Vicky Brit, Special Interest both basically gave me the old 
S-O-L answer.
     
Anyone have any ideas where i can find them, or have faced (and 
overcome) this themselves.  The parts numbers that were found are
     
2A4008            .012"
2A4007            .008"
2A4168            .003"
     
Thanks,
     
Patton
